Good point. Certain perl functions return "0E" when they mean "0", so that
it can be treated as 'true'.

Just remember that Ruby isn't Perl or C. It doesn't take long to get used to
it, and you'll find it's much cleaner. After all, why should the number "0"
be treated differently from the number "1"?
