Good point.  You're right.  I forgot about that.  

It seems that I've to explain what I want to achieve.  I was
experimenting to add generic functions and multi methods to Ruby.  To
make them useful, I need types.  

I wanted to use the classes as types (the natural way most languages
go) but then stumbled across the problem, that there's no Boolean
class and therefore no boolean type.

However, making the type hierarchy independent from the class (and
module) hierarchy is probably the better approach anyway.
