Saying it's a "gotcha" makes it sound like the behavior is wrong.  Some 
would say that only false should be false.  Me, I like that nil is 
false, but I sure as hell don't want 0 or '' or [] or {} to be false. 
It behaves well -- that's not a gotcha -- that's just good common sense.

I can't quite tell what you're looking for exactly, but String#match is 
probably it.  (I don't like the =~ perlism myself).
