Perl, abusing defined since 1989:
$ ./perl -e 'sub def {print defined $a ? "Yes\n" : "No\n";}' -e '&def(); $a = "$]\n"; &def();'
No
Yes
$ ./perl -e 'print "$]\n";'

[Perl 3 doesn't like building on anything. Even AIX.
It also seems to be very fussy about newlines after subroutine definitions.
The world must have been very different 22 years ago.
But it doesn't surprise me that Perl has pedigree in "doing it wrong". As
only a mongrel can.]
