must either both be scalars or both be lists. Otherwise Perl won't
know which context to supply to the right side.
-=item Attempt to access key '%_' in fixed hash
+=item Attempt to access disallowed key '%s' in a 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
-has attempted to get or set the value of a key which does not
-exist or to delete a key.
+(F) The failing code has attempted to get or set a key which is not in
+the current set of allowed keys of a fixed hash.
+
+=item Attempt to clear a fixed hash
+
+(F) It is currently not allowed to clear a fixed hash, even if the
+new hash would contain the same keys as before. This may change in
+the future.
+
+=item Attempt to delete readonly key '%s' from a fixed hash
+
+(F) The failing code attempted to delete a key whose value has been
+declared readonly from a fixed hash.
+
+=item Attempt to delete disallowed key '%s' from a fixed hash
+
+(F) The failing code attempted to delete from a fixed hash a key which
+is not in its key set.
=item Attempt to bless into a reference
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.
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.
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
(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
