(F) The '!' is allowed in pack() and unpack() only after certain types.
See L<perlfunc/pack>.
+=item # cannot take a count
+
+(F) You had an unpack template indicating a counted-length string,
+but you have also specified an explicit size for the string.
+See L<perlfunc/pack>.
+
+=item # must be followed by a, A or Z
+
+(F) You had an unpack template indicating a counted-length string,
+which must be followed by one of the letters a, A or Z
+to indicate what sort of string is to be unpacked.
+See L<perlfunc/pack>.
+
+=item # must be followed by a*, A* or Z*
+
+(F) You had an pack template indicating a counted-length string,
+Currently the only things that can have their length counted are a*, A* or Z*.
+See L<perlfunc/pack>.
+
+=item # must follow a numeric type
+
+(F) You had an unpack template that contained a '#',
+but this did not follow some numeric unpack specification.
+See L<perlfunc/pack>.
+
=item % may only be used in unpack
(F) You can't pack a string by supplying a checksum, because the
by parentheses turns into a function, with all the list operators arguments
found inside the parentheses. See L<perlop/Terms and List Operators (Leftward)>.
+=item %s() called too early to check prototype
+
+(W) You've called a function that has a prototype before the parser saw a
+definition or declaration for it, and Perl could not check that the call
+conforms to the prototype. You need to either add an early prototype
+declaration for the subroutine in question, or move the subroutine
+definition ahead of the call to get proper prototype checking. Alternatively,
+if you are certain that you're calling the function correctly, you may put
+an ampersand before the name to avoid the warning. See L<perlsub>.
+
=item %s argument is not a HASH element
(F) The argument to exists() must be a hash element, such as
(F) You had a pack template that specified an absolute position outside
the string being unpacked. See L<perlfunc/pack>.
+=item <> should be quotes
+
+(F) You wrote C<require E<lt>fileE<gt>> when you should have written
+C<require 'file'>.
+
=item accept() on closed fd
(W) You tried to do an accept on a closed socket. Did you forget to check
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 join self
+
+(F) You tried to join a thread from within itself, which is an
+impossible task. You may be joining the wrong thread, or you may
+need to move the join() to some other thread.
+
=item Attempt to pack pointer to temporary value
(W) You tried to pass a temporary value (like the result of a
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
+=item Can't locate %s
-(F) You said to do (or require, or use) a file that couldn't be found
-in any of the libraries mentioned in @INC. Perhaps you need to set the
-PERL5LIB or PERL5OPT environment variable to say where the extra library
-is, or maybe the script needs to add the library name to @INC. Or maybe
-you just misspelled the name of the file. See L<perlfunc/require>.
+(F) You said to C<do> (or C<require>, or C<use>) a file that couldn't be
+found. Perl looks for the file in all the locations mentioned in @INC,
+unless the file name included the full path to the file. Perhaps you need
+to set the PERL5LIB or PERL5OPT environment variable to say where the extra
+library is, or maybe the script needs to add the library name to @INC. Or
+maybe you just misspelled the name of the file. See L<perlfunc/require>
+and L<lib>.
=item Can't locate object method "%s" via package "%s"
subscript. But to the left of the brackets was an expression that
didn't look like an array reference, or anything else subscriptable.
+=item Can't weaken a nonreference
+
+(F) You attempted to weaken something that was not a reference. Only
+references can be weakened.
+
=item Can't x= to read-only value
(F) You tried to repeat a constant value (often the undefined value) with
an assignment operator, which implies modifying the value itself.
Perhaps you need to copy the value to a temporary, and repeat that.
-=item Cannot find an opnumber for "%s"
+=item Can't find an opnumber for "%s"
(F) A string of a form C<CORE::word> was given to prototype(), but
there is no builtin with the name C<word>.
-=item Cannot resolve method `%s' overloading `%s' in package `%s'
+=item Can't resolve method `%s' overloading `%s' in package `%s'
(F|P) Error resolving overloading specified by a method name (as
opposed to a subroutine reference): no such method callable via the
package. If method name is C<???>, this is an internal error.
+=item Character class [:%s:] unknown
+
+(F) The class in the character class [: :] syntax is unknown.
+
+=item Character class syntax [%s] belongs inside character classes
+
+(W) The character class constructs [: :], [= =], and [. .] go
+I<inside> character classes, the [] are part of the construct,
+for example: /[012[:alpha:]345]/. Note that the last two constructs
+are not currently implemented, they are placeholders for future extensions.
+
=item Character class syntax [. .] is reserved for future extensions
(W) Within regular expression character classes ([]) the syntax beginning
expression character class, just quote the square brackets with the
backslash: "\[." and ".\]".

-
-(W) Within regular expression character classes ([]) the syntax beginning
-with "[:" and ending with ":]" is reserved for future extensions.
-If you need to represent those character sequences inside a regular
-expression character class, just quote the square brackets with the
-backslash: "\[:" and ":\]".

=item Character class syntax [= =] is reserved for future extensions
(W) Within regular expression character classes ([]) the syntax
recursion, unless you're writing strange benchmark programs, in which
case it indicates something else.
+=item defined(@array) is deprecated
+
+(D) defined() is not usually useful on arrays because it checks for an
+undefined I<scalar> value. If you want to see if the array is empty,
+just use C<if (@array) { # not empty }> for example.
+
+=item defined(%hash) is deprecated
+
+(D) defined() is not usually useful on hashes because it checks for an
+undefined I<scalar> value. If you want to see if the hash is empty,
+just use C<if (%hash) { # not empty }> for example.
+
=item Delimiter for here document is too long
(F) In a here document construct like C<E<lt>E<lt>FOO>, the label
You need to do an open() or a socket() call, or call a constructor from
the FileHandle package.
-=item Filehandle %s opened for only input
+=item Filehandle %s opened only for input
(W) You tried to write on a read-only filehandle. If you
intended it to be a read-write filehandle, you needed to open it with

L<perlfunc/open>.
-=item Filehandle opened for only input
+=item Filehandle %s opened only for output
-(W) You tried to write on a read-only filehandle. If you
+(W) You tried to read from a filehandle opened only for writing. If you
intended it to be a read-write filehandle, you needed to open it with
"+E<lt>" or "+E<gt>" or "+E<gt>E<gt>" instead of with "E<lt>" or nothing. If
-you intended only to write the file, use "E<gt>" or "E<gt>E<gt>". See
+you intended only to read from the file, use "E<lt>". See
L<perlfunc/open>.
=item Final $ should be \$ or $name
(W) You redefined a format. To suppress this warning, say
{
- local $^W = 0;
+ no warning;
eval "format NAME =...";
}
(W) You may have tried to use an 8 or 9 in a octal number. Interpretation
of the octal number stopped before the 8 or 9.
-=item Illegal hex digit %s ignored
+=item Illegal hexadecimal digit %s ignored
(W) You may have tried to use a character other than 0 - 9 or A - F in a
hexadecimal number. Interpretation of the hexadecimal number stopped
=item Integer overflow in %s number
-(S) The literal hex, octal or binary number you have specified is
-too big for your architecture. On a 32-bit architecture the largest
+(S) The literal hexadecimal, octal or binary number you have specified
+is too big for your architecture. On a 32-bit architecture the largest
literal hex, octal or binary number representable without overflow
is 0xFFFFFFFF, 037777777777, or 0b11111111111111111111111111111111
respectively. Note that Perl transparently promotes decimal literals

timezone offset, so it's assuming that local system time is equivalent
to UTC. If it's not, define the logical name F<SYS$TIMEZONE_DIFFERENTIAL>
to translate to the number of seconds which need to be added to UTC to
(P) The savestack was requested to restore more localized values than there
are in the savestack.
+=item panic: del_backref
+
+(P) Failed an internal consistency check while trying to reset a weak
+reference.
+
=item panic: die %s
(P) We popped the context stack to an eval context, and then discovered
(P) Something requested a negative number of bytes of malloc.
+=item panic: magic_killbackrefs
+
+(P) Failed an internal consistency check while trying to reset all weak
+references to an object.
+
=item panic: mapstart
(P) The compiler is screwed up with respect to the map() function.
One possible workaround is to force Perl to use magical string
increment by prepending "0" to your numbers.
-=item Read on closed filehandle E<lt>%sE<gt>
+=item Read on closed filehandle %s
(W) The filehandle you're reading from got itself closed sometime before now.
Check your logic flow.
%hash = ( one => 1, two => 2, ); # right

+ no warning;
eval "sub name { ... }";
}
(F) There are no byte-swapping functions for a machine with this byte order.
+=item Unknown open() mode '%s'
