Okay...

To begin with, I'm related to this kid, so take what I say with a grain of salt.

But.

TMTOWTDI.

End of story. Anybody who's used LISP knows that this is a great feature. Subroutines that evaluate to true or false should be distinguished from ones that return a value.

is_female() should return an object of type female or FALSE. is_female?() should simply return TRUE or FALSE. It's faster, you can short-circuit up the ying-yang and it's just generally better.

Some implementations of LISP use conventions like is_femalep (stands for predicate) and that's pretty nice too. All in all, you should be able to do this sort of thing in Perl, because TMTOWTDI.

My two cents,
David.
