I just tried and it works. I also tried to break it when creating  
subclasses, but I was not successful.
Let's assume a class A, for which:
A class>>initialize
	" do nothing"

I was wondering why I can still create a subclass of A.

Actually, when a subclass is created, Behavior>>new is called on the  
class Metaclass. Then, this instance of Metaclass is initialized with  
a superclass and an empty dictionary
