=head1 NAME
perldiag - various Perl diagnostics
must either both be scalars or both be lists. Otherwise Perl won't
know which context to supply to the right side.
-=item Negative offset to vec in lvalue context
-
-(F) When C<vec> is called in an lvalue context, the second argument must be
-greater than or equal to zero.
-
-=item Attempt to access to key '%_' in fixed hash
+=item Attempt to access key '%_' in fixed hash
(F) A hash has been marked as READONLY at the C level to turn it
into a "record" with a fixed set of keys. The failing code
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 %s defines neither package nor VERSION--version check failed
+
+(F) You said something like "use Module 42" but in the Module file
+there are neither package declarations nor a C<$VERSION>.
+
=item Delimiter for here document is too long
(F) In a here document construct like C<<<FOO>, the label C<FOO> is too
See Server error.
+=item %s does not define %s::VERSION--version check failed
+
+(F) You said something like "use Module 42" but the Module did not
+define a C<$VERSION.>
+
=item Don't know how to handle magic of type '%s'
(P) The internal handling of magical variables has been cursed.
filenames, try using the glob() operator, or put the filenames into a
variable and glob that.
+=item exec? I'm not *that* kind of operating system
+
+(F) The C<exec> function is not implemented in MacPerl. See L<perlport>.
+
=item Execution of %s aborted due to compilation errors
(F) The final summary message when a Perl compilation fails.
Failure of user callbacks dispatched using the C<G_KEEPERR> flag could
also result in this warning. See L<perlcall/G_KEEPERR>.
+=item In EBCDIC the v-string components cannot exceed 2147483647
+
+(F) An error peculiar to EBCDIC. Internally, v-strings are stored as
+Unicode code points, and encoded in EBCDIC as UTF-EBCDIC. The UTF-EBCDIC
+encoding is limited to code points no larger than 2147483647 (0x7FFFFFFF).
+
=item Insecure dependency in %s
(F) You tried to do something that the tainting mechanism didn't like.
you omitted the name of the module. Consult L<perlrun> for full details
about C<-M> and C<-m>.
+=item More than one argument to open
+
+(F) The C<open> function has been asked to open multiple files. This
+can happen if you are trying to open a pipe to a command that takes a
+list of arguments, but have forgotten to specify a piped open mode.
+See L<perlfunc/open> for details.
+
=item msg%s not implemented
(F) You don't have System V message IPC on your system.
(F) You tried to do a read/write/send/recv operation with a buffer
length that is less than 0. This is difficult to imagine.
+=item Negative offset to vec in lvalue context
+
+(F) When C<vec> is called in an lvalue context, the second argument must be
+greater than or equal to zero.
+
=item Nested quantifiers in regex; marked by <-- HERE in m/%s/
(F) You can't quantify a quantifier without intervening parentheses. So
some day, even though it doesn't yet. Perhaps you should use a
mixed-case attribute name, instead. See L<attributes>.
-=item Package '%s' not found (did you use the incorrect case?)
-
-(W misc) You included a package file via C<use>, but the package name
-did not match the file name. It's possible that you misspelled the
-package name.
-
=item page overflow
(W io) A single call to write() produced more lines than can fit on a
(S prototype) The subroutine being declared or defined had previously been
declared or defined with a different function prototype.
+=item Prototype not terminated
+
+(F) You've omitted the closing parenthesis in a function prototype
+definition.
+
=item Quantifier in {,} bigger than %d in regex;
marked by <-- HERE in m/%s/
(F) A sort comparison subroutine may not return a list value with more
or less than one element. See L<perlfunc/sort>.
+=item splice() offset past end of array
+
+(W misc) You attempted to specify an offset that was past the end of
+the array passed to splice(). Splicing will instead commence at the end
+of the array, rather than past it. If this isn't what you want, try
+explicitly pre-extending the array by assigning $#array = $offset. See
+L<perlfunc/splice>.
+
=item Split loop
(P) The split was looping infinitely. (Obviously, a split shouldn't
