This is something I think would be useful in some way, but I'm not sure
how to integrate it in a Pythonic way.

So what would private and public scopes get you that name mangling
wouldn't?

Can't you do this yourself?

You already have these.

You have these too:

	class C:
	    N = 0
	    def __init__(self):
	        C.N += 1

The C.N counter is common to all instances.

This is a common request, but the problem in some cases the self
argument _can't_ be implicit.  Take, for instance, bound vs. unbound
methods.  Sometimes the self argument needs to be explicit.
