you tried to jump out of a sort() block or subroutine, which is a no-no.
See L<perlfunc/goto>.
-=item Can't goto subroutine from an eval-string
+=item Can't goto subroutine from an eval-%s
(F) The "goto subroutine" call can't be used to jump out of an eval
-"string". (You can use it to jump out of an eval {BLOCK}, but you
-probably don't want to.)
+"string" or block.
=item Can't goto subroutine outside a subroutine
=item No DB::DB routine defined
(F) The currently executing code was compiled with the B<-d> switch, but
-for some reason the perl5db.pl file (or some facsimile thereof) didn't
-define a routine to be called at the beginning of each statement. Which
-is odd, because the file should have been required automatically, and
-should have blown up the require if it didn't parse right.
+for some reason the current debugger (e.g. F<perl5db.pl> or a C<Devel::>
+module) didn't define a routine to be called at the beginning of each
+statement.
=item No dbm on this machine
(P) This is counted as an internal error, because every machine should
supply dbm nowadays, because Perl comes with SDBM. See L<SDBM_File>.
-=item No DBsub routine
+=item No DB::sub routine defined
-(F) The currently executing code was compiled with the B<-d> switch,
-but for some reason the perl5db.pl file (or some facsimile thereof)
-didn't define a DB::sub routine to be called at the beginning of each
-ordinary subroutine call.
+(F) The currently executing code was compiled with the B<-d> switch, but
+for some reason the current debugger (e.g. F<perl5db.pl> or a C<Devel::>
+module) didn't define a C<DB::sub> routine to be called at the beginning
+of each ordinary subroutine call.
=item No B<-e> allowed in setuid scripts
(S internal) An internal warning that the grammar is screwed up.
-=item Operation `%s': no method found, %s
+=item Operation "%s": no method found, %s
(F) An attempt was made to perform an overloaded operation for which no
handler was defined. While some handlers can be autogenerated in terms
(W unopened) You tried to use the stat() function on a filehandle that
was either never opened or has since been closed.
-=item Stub found while resolving method `%s' overloading %s
+=item Stub found while resolving method "%s" overloading "%s"
(P) Overloading resolution over @ISA tree may be broken by importation
stubs. Stubs should never be implicitly created, but explicit calls to
