I just looked at your suggestion again. IMHO, I think my idea of using 
categories for native methods is more elegant. You map native methods to 
function calls. When you implement a native instance method you also 
need to explicitly pass the 'self' reference. You get all that for free 
with categories and you don't have to map native methods to functions. 
If you don't implement a native method, I throw an exception.
