Modification of builtin types using classes

[PlaceReporter99]

Feature or enhancement

I would like it so that when I do something like class str(builtin=True), any functions and other things defined in the class apply to the built-in class, and therefore literals.

Pitch

With a built-in type, you may decide to not implement a few class methods for that type. Adding this would allow users who want those class methods to implement them.

I'm going to close this unless and until a consensus comes out of the discussion on discuss.python.org. This will also need a PEP, so an issue isn't much use yet.

If we get as far as implementing this, we can re-open this issue.
