Some of these messages are generic. Spots that vary are denoted with a %s,
just as in a printf format. Note that some messages start with a %s!

instead of Perl. Check the #! line, or manually feed your script
into Perl yourself.
+=item (Missing semicolon on previous line?)
+
+(S) This is an educated guess made in conjunction with the message "%s
+found where operator expected". Don't automatically put a semicolon on
+the previous line just because you saw this message.
+
=item B<-P> not allowed for setuid/setgid script
(F) The script would have to be opened by the C preprocessor by name,
(F) Perl can't peek at the stdio buffer of filehandles when it doesn't
know about your kind of stdio. You'll have to use a filename instead.
+=item C<-p> destination: %s
+
+(F) An error occurred during the implicit output invoked by the C<-p>
+command-line switch. (This output goes to STDOUT unless you've
+redirected it with select().)
+
=item 500 Server error
See Server error.
SvREFCNT_inc() was called too few times, or that the SV was mortalized
when it shouldn't have been, or that memory has been corrupted.
+=item Attempt to pack pointer to temporary value
+
+(W) You tried to pass a temporary value (like the result of a
+function, or a computed expression) to the "p" pack() template. This
+means the result contains a pointer to a location that could become
+invalid anytime, even before the end of the current statement. Use
+literals or global values as arguments to the "p" pack() template to
+avoid this warning.
+
=item Attempt to use reference as lvalue in substr
(W) You supplied a reference as the first argument to substr() used
occurs if you tried to jump out of a sort() block or subroutine, which
is a no-no. See L<perlfunc/goto>.
+=item Can't "goto" into the middle of a foreach loop
+
+(F) A "goto" statement was executed to jump into the middle of a
+foreach loop. You can't get there from here. See L<perlfunc/goto>.
+
=item Can't "last" outside a block
(F) A "last" statement was executed to break out of the current block,
=item Can't execute %s
+(F) You used the B<-S> switch, but the copies of the script to execute found
+in the PATH did not have correct permissions.
+
+=item Can't find %s on PATH, '.' not in PATH
+
+(F) You used the B<-S> switch, but the script to execute could not be found
+in the PATH, or at least not with the correct permissions. The script
+exists in the current directory, but PATH prohibits running it.
+
+=item Can't find %s on PATH
+
(F) You used the B<-S> switch, but the script to execute could not be found
-in the PATH, or at least not with the correct permissions.
+in the PATH.
=item Can't find label %s
you should be calling it out of only an AUTOLOAD routine anyway. See
L<perlfunc/goto>.
-=item Can't localize a reference
+=item Can't localize through a reference
-(F) You said something like C<local $$ref>, which is not allowed because
-the compiler can't determine whether $ref will end up pointing to anything
-with a symbol table entry, and a symbol table entry is necessary to
-do a local.
+(F) You said something like C<local $$ref>, which Perl can't currently
+handle, because when it goes to restore the old value of whatever $ref
+pointed to after the scope of the local() is finished, it can't be
+sure that $ref will still be a reference.
=item Can't localize lexical variable %s
localize a package variable of the same name, qualify it with the
package name.
+=item Can't locate auto/%s.al in @INC
+
+(F) A function (or method) was called in a package which allows autoload,
+but there is no function to autoload. Most probable causes are a misprint
+in a function/method name or a failure to C<AutoSplit> the file, say, by
+doing C<make install>.
+
=item Can't locate %s in @INC
(F) You said to do (or require, or use) a file that couldn't be found
(W) The @ISA array contained the name of another package that doesn't seem
to exist.
+=item Can't make list assignment to \%ENV on this system
+
+(F) List assignment to %ENV is not supported on some systems, notably VMS.
+
=item Can't mktemp()
(F) The mktemp() routine failed for some reason while trying to process
=item Can't open %s: %s
-(S) An inplace edit couldn't open the original file for the indicated reason.
-Usually this is because you don't have read permission for the file.
+(S) The implicit opening of a file through use of the C<E<lt>E<gt>>
+filehandle, either implicitly under the C<-n> or C<-p> command-line
+switches, or explicitly, failed for the indicated reason. Usually this
+is because you don't have read permission for a file which you named
+on the command line.
=item Can't open bidirectional pipe
(F) The script you specified can't be opened for the indicated reason.
+=item Can't redefine active sort subroutine %s
+
+(F) Perl optimizes the internal handling of sort subroutines and keeps
+pointers into them. You tried to redefine one such sort subroutine when it
+was currently active, which is not allowed. If you really want to do
+this, you should write C<sort { &func } @x> instead of C<sort func @x>.
+
=item Can't rename %s to %s: %s, skipping file
(S) The rename done by the B<-i> switch failed for some reason, probably because
=item Deep recursion on subroutine "%s"
(W) This subroutine has called itself (directly or indirectly) 100
-times than it has returned. This probably indicates an infinite
+times more than it has returned. This probably indicates an infinite
recursion, unless you're writing strange benchmark programs, in which
case it indicates something else.
+=item Delimiter for here document is too long
+
+(F) In a here document construct like C<E<lt>E<lt>FOO>, the label
+C<FOO> is too long for Perl to handle. You have to be seriously
+twisted to write code that triggers this error.
+
=item Did you mean &%s instead?
(W) You probably referred to an imported subroutine &FOO as $FOO or some such.
passed an invalid file specification to Perl, or you've found a
case the conversion routines don't handle. Drat.
+=item Excessively long <> operator
+
+(F) The contents of a <> operator may not exceed the maximum size of a
+Perl identifier. If you're just trying to glob a long list of
+filenames, try using the glob() operator, or put the filenames into a
+variable and glob that.
+
=item Execution of %s aborted due to compilation errors
(F) The final summary message when a Perl compilation fails.
(D) Really old Perl let you omit the % on hash names in some spots. This
is now heavily deprecated.
+=item Identifier too long
+
+(F) Perl limits identifiers (names for variables, functions, etc.) to
+about 250 characters for simple names, and somewhat more for compound
+names (like C<$A::B>). You've exceeded Perl's limits. Future
+versions of Perl are likely to eliminate these arbitrary limitations.
+
=item Ill-formed logical name |%s| in prime_env_iter
(W) A warning peculiar to VMS. A logical name was encountered when preparing
(F) The range specified in a character class had a minimum character
greater than the maximum character. See L<perlre>.
+=item Invalid conversion in %s: "%s"
+
+(W) Perl does not understand the given format conversion.
+See L<perlfunc/sprintf>.
+
+=item Invalid type in pack: '%s'
+
+(F) The given character is not a valid pack type. See L<perlfunc/pack>.
+
+=item Invalid type in unpack: '%s'
+
+(F) The given character is not a valid unpack type. See L<perlfunc/unpack>.
+
=item ioctl is not implemented
(F) Your machine apparently doesn't implement ioctl(), which is pretty
As a general rule, you'll find it's missing near the place you were last
editing.
-=item Missing semicolon on previous line?
-
-(S) This is an educated guess made in conjunction with the message "%s
-found where operator expected". Don't automatically put a semicolon on
-the previous line just because you saw this message.
-
=item Modification of a read-only value attempted
(F) You tried, directly or indirectly, to change the value of a
(P) The internal pattern matching routines are out of their gourd.
+=item Number too long
+
+(F) Perl limits the representation of decimal numbers in programs to about
+about 250 characters. You've exceeded that length. Future versions of
+Perl are likely to eliminate this arbitrary limitation. In the meantime,
+try using scientific notation (e.g. "1e6" instead of "1_000_000").
+
=item Odd number of elements in hash list
(S) You specified an odd number of elements to a hash list, which is odd,
(P) The internal do_trans() routine was called with invalid operational data.
+=item panic: frexp
+
+(P) The library function frexp() failed, making printf("%f") impossible.
+
=item panic: goto
(P) We popped the context stack to a context with the specified label,
(F) The lexer couldn't find the final delimiter of a // or m{}
construct. Remember that bracketing delimiters count nesting level.
-=item seek() on unopened file
+=item %sseek() on unopened file
-(W) You tried to use the seek() function on a filehandle that was either
-never opened or has since been closed.
+(W) You tried to use the seek() or sysseek() function on a filehandle that
+was either never opened or has since been closed.
=item select not implemented
(W) The filehandle you're sending to got itself closed sometime before now.
Check your logic flow.
+=item Sequence (? incomplete
+(F) A regular expression ended with an incomplete extension (?.
+See L<perlre>.
+
=item Sequence (?#... not terminated
(F) A regular expression comment must be terminated by a closing
=item setruid() not implemented
-(F) You tried to assign to C<$<lt>>, and your operating system doesn't support
+(F) You tried to assign to C<$E<lt>>, and your operating system doesn't support
the setruid() system call (or equivalent), or at least Configure didn't
think so.
=item substr outside of string
-(W) You tried to reference a substr() that pointed outside of a string.
-That is, the absolute value of the offset was larger than the length of
-the string. See L<perlfunc/substr>.
+(S),(W) You tried to reference a substr() that pointed outside of a
+string. That is, the absolute value of the offset was larger than the
+length of the string. See L<perlfunc/substr>. This warning is
+mandatory if substr is used in an lvalue context (as the left hand side
+of an assignment or as a subroutine argument for example).
=item suidperl is no longer needed since %s
(W) The filehandle you're writing to got itself closed sometime before now.
Check your logic flow.
+=item Target of goto is too deeply nested
+
+(F) You tried to use C<goto> to reach a label that was too deeply
+nested for Perl to reach. Perl is doing you a favor by refusing.
+
=item tell() on unopened file
(W) You tried to use the tell() function on a filehandle that was either
(F) You specified a signal name to the kill() function that was not recognized.
Say C<kill -l> in your shell to see the valid signal names on your system.
-=item Unrecognized switch: -%s
+=item Unrecognized switch: -%s (-h will show valid options)
(F) You specified an illegal option to Perl. Don't do that.
(If you think you didn't do that, check the #! line to see if it's
