Better expression for $x = !!$y||0
Except Perl 5 makes no such guarantee. A lot of the built-ins return
""
or 1 instead, for instance.

Do you mean sv_yes or sv_no (which has PV "" and IV 0)? Or the very few things that actually return either "" or 0 instead of sv_no? IIRC correctly, there are good reasons for those odd cases.
