=item Bareword in require contains "%s"

-
=item Bareword in require maps to disallowed filename "%s"
+=item Bareword in require maps to empty filename
(F) The bareword form of require has been invoked with a filename which could
not have been generated by a valid bareword permitted by the parser. You
use feature "signatures";
sub foo ($left, $right) { ... }
-=item Experimental "%s" subs not enabled
-
-(F) To use lexical subs, you must first enable them:
-
- no warnings 'experimental::lexical_subs';
- use feature 'lexical_subs';
- my sub foo { ... }
-
=item Explicit blessing to '' (assuming package main)
(W misc) You are blessing a reference to a zero length string. This has
a reference to something else instead. You can use the ref() function
to find out what kind of ref it really was. See L<perlref>.
-=item Not an unblessed ARRAY reference
-
-(F) You passed a reference to a blessed array to C<push>, C<shift> or
-another array function. These only accept unblessed array references
-or arrays beginning explicitly with C<@>.
-
=item Not a SCALAR reference
(F) Perl was trying to evaluate a reference to a scalar value, but found
for I/O (in anticipation of future reads and to imitate the behavior
with real files).
+=item Only one /x regex modifier is allowed
+
+=item Only one /x regex modifier is allowed in regex; marked by <-- HERE in m/%s/
+
+(F) You used the C</x> regular expression pattern modifier at least twice in a
+string of modifiers. This has been made illegal, in order to allow future
+extensions to the Perl language.
+
=item %s() on unopened %s
(W unopened) An I/O operation was attempted on a filehandle that was
(W unopened) You tried to invoke a file test operator on a filehandle
that isn't open. Check your control flow. See also L<perlfunc/-X>.
-=item Only one /x regex modifier is allowed
-
-=item Only one /x regex modifier is allowed in regex; marked by <-- HERE in m/%s/
-
-(F) You used the C</x> regular expression pattern modifier at least
-twice in a string of modifiers. It is illegal to do this with, to allow
-future extensions to the Perl language.
-
=item oops: oopsAV
(S internal) An internal warning that the grammar is screwed up.
(P) The compiler is screwed up and attempted to use an op that isn't
permitted at run time.
+=item panic: unknown OA_*: %x
+
+(P) The internal routine that handles arguments to C<&CORE::foo()>
+subroutine calls was unable to determine what type of arguments
+were expected.
+
=item panic: utf16_to_utf8: odd bytelen
(P) Something tried to call utf16_to_utf8 with an odd (as opposed
(F) The function indicated isn't implemented on this architecture,
according to the probings of Configure.
-=item The lexical_subs feature is experimental
-
-(S experimental::lexical_subs) This warning is emitted if you
-declare a sub with C<my> or C<state>. Simply suppress the warning
-if you want to use the feature, but know that in doing so you
-are taking the risk of using an experimental feature which may
-change or be removed in a future Perl version:
-
- no warnings "experimental::lexical_subs";
- use feature "lexical_subs";
- my sub foo { ... }
-
=item The regex_sets feature is experimental
(S experimental::regex_sets) This warning is emitted if you
came from. If you really really know what you are doing you can turn
off this warning by C<no warnings 'surrogate';>.
-=item Unknown charname '' is deprecated
-
-(D deprecated) You had a C<\N{}> with nothing between the braces. This
-usage is deprecated, and will be made a syntax error in a future Perl
-version.
-
=item Unknown charname '%s'
(F) The name you used inside C<\N{}> is unknown to Perl. Check the
also happen if the C<\N{}> is not in the scope of the corresponding
C<S<use charnames>>.
+=item Unknown charname '' is deprecated
+
+(D deprecated) You had a C<\N{}> with nothing between the braces. This
+usage is deprecated, and will be made a syntax error in a future Perl
+version.
+
=item Unknown error
(P) Perl was about to print an error message in C<$@>, but the C<$@> variable
(F) You used a verb pattern that is not allowed an argument. Remove the
argument or check that you are using the right verb.
+=item Version control conflict marker '%s'
+
+(F) The parser found a line starting with C<E<lt><<<<<<>,
+C<E<gt>E<gt>E<gt>E<gt>E<gt>E<gt>E<gt>>, or C<=======>. These may be left by a
+version control system to mark conflicts after a failed merge operation.
+
=item Version number must be a constant number
(P) The attempt to translate a C<use Module n.n LIST> statement into
