The implementation I'm talking about that would have a constant PI=3.1415 
within say MyClass would only work if called as MyClass.PI

In your example, the global PI would always be defined unless somebody 
redifines it, and then it's not a class constant anyway. 

if OOP is about data encapsulation, why are we using global constants and 
types?
