Ok, thank you, that cleared things. I have two follow up questions:
1. If I want to add an instance variable to an object of class C I can
only do that in a method (not as part of the class definition)? In the 
example above, how can I change it so that C.new will return an instance 
of C where '@x' of the instance is 1?
2. Is there an analogous way to 'initialize' to write initialization of 
class variables?

Thank you,
Ittay
