Zero is also false, that is true, but a true boolean expression
in perl returns undef or one, not zero or one. (Sorry, I can't
help it. Writing about boolean logic just makes it too easy to
play on words... :-)
Booleans produce an empty string, not undef, for false. That can
easily be produced without hardcoding FALSE by having it be
!TRUE. As I've already said. :)
I stand corrected.
But the shame of it! Here I've been programming perl since the early
90's, and always thought that boolean operations returned undef for
false. Well, I guess I'll live through this one also....
Thanks for setting the records straight.
