Do any of the subs do some sort of conditional import into main or muck with
the symbol table?
For example:
use 5.12.1;
sub foo { say 'test' }
if (rand > 0.5) {
undef *{foo};
}
foo();
50% of the time will print "test" and the other 50% will print:
Undefined subroutine &main::foo called at test.pl line 8.
