Yes, and for lexical hashes you get a compile-time warning:
$ perl -wce 'my %foo; print defined %foo'
defined(%hash) is deprecated at -e line 1.
(Maybe you should just omit the defined()?)
although interestingly in Perl_ck_defined where it emits those warnings,
it has:
case OP_RV2HV:
/* This is needed for
if (defined %stash::)
to work. Do not break Tk.
*/
break; /* Globals via GV can be undef */
Sounds like we've broken Tk.....
