That's a mistake... the same one Ruby and Perl made. Only Smalltalk gets that right. it'd be ok if I could at least override "asBoolean" for my classes as far as ifTrue: and ifFalse: are concerned, but no. Io has its own idea, and that's that. And I can't even get it to throw a "must be boolean" error instead. Sigh. So close, and yet so far away. It’s too bad Io has an implicit non-overridable “asBoolean” method in the Object base class.
