Getting rid of C-coded types is certainly an interesting requirement as 
well. I hope PyPythonistas may agree :)

Honestly, I don't understand how a pointer on an implicit/interpreter 
level Trait that stores user defined methods for builtins would slow 
execution down. You would need wrappers only if you permit 
replacing/deleting pre-defined methods and I don't see reasons to be 
permissive here.
