-(W) When using threaded Perl, a thread (not necessarily the main
+(W threads)(S) When using threaded Perl, a thread (not necessarily the main
thread) exited while there were still other threads running.
Usually it's a good idea to first collect the return values of the
created threads by joining them, and only then exit from the main
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 property definition %s
-
-(F) You may have tried to use C<\p> which means a Unicode property (for
-example C<\p{Lu}> is all uppercase letters). If you did mean to use a
-Unicode property, see L<perlunicode> for the list of known properties.
-If you didn't mean to use a Unicode property, escape the C<\p>, either
-by C<\\p> (just the C<\p>) or by C<\Q\p> (the rest of the string, until
-possible C<\E>).
-
=item Can't find string terminator %s anywhere before EOF
(F) Perl strings can stretch over multiple lines. This message means
unseen whitespace before or after your closing tag. A good programmer's
editor will have a way to help you find these characters.

See L<perlfunc/goto>.
+=item Can't goto subroutine from a sort sub (or similar callback)
+
+(F) The "goto subroutine" call can't be used to jump out of the
+comparison sub for a sort(), or from a similar callback (such

=item Can't goto subroutine from an eval-%s
(F) The "goto subroutine" call can't be used to jump out of an eval
or define F<PERL_ENV_TABLES> (see L<perlvms>) so that environ is not
searched.
-=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>.

length/code combination tried to obtain more data. This results in
an undefined value for the length. See L<perlfunc/pack>.
=item Malformed UTF-8 character (%s)
-(W utf8) Perl detected something that didn't comply with UTF-8 encoding rules.
+(S utf8) (F) Perl detected something that didn't comply with UTF-8
+encoding rules.
One possible cause is that you read in data that you thought to be in
UTF-8 but it wasn't (it was for example legacy 8-bit data). Another
F<SYS$TIMEZONE_DIFFERENTIAL> to translate to the number of seconds which
need to be added to UTC to get local time.

+=item panic: attempt to call %s in %s

+(P) One of the file test operators entered a code branch that calls
+an ACL related-function, but that function is not available on this

=item panic: ck_grep
(P) Failed an internal consistency check trying to compile a grep.
(P) Something requested a negative number of bytes of malloc.

+(W threads)(S) The entry point function of threads->create() failed for some reason.
=item times not implemented
This warning will not be issued for numerical constants equal to 0 or 1
since they are often used in statements like
- 1 while sub_with_side_effects() ;
+ 1 while sub_with_side_effects();
String constants that would normally evaluate to 0 or 1 are warned
about.
(F) You had a pack template that specified a relative position after
the end of the string being unpacked. See L<perlfunc/pack>.
