superclasses like python?

Ruby does support it 😉 It just looks a bit different and is called  
mixin’s: [http://www.rubycentral.com/book/tut\_modules.html](http://www.rubycentral.com/book/tut_modules.html) but at least  
from the point where I can say it at the moment, it feels in use exaclty  
like multiple inheritances.
