I'm looking for an explanation of how explicit self is implimented
It's not "implemented" - it's just the first argument of the function, and you have to declare it explicitely in the function's args list.
If your question is about how "obj.func()" becomes "obj.___class__.func(obj)", then the answer is "protocol deescriptor" + "method type". The function type implements the protocol descriptor so that its __get__ method returns a method instance which wraps around the function, class and instance. Then the method's __call__ method will delegate to the function, injecting the instance as first positional param.
and what features are only possible because of, or are greatly improved, because of it.
Simplicity (methods are built of the combination of two "general purpose" features - descriptor protocol and callable objects), flexibility (you can use any callable object as a 'method' as long as it correctly implements the descriptor protocol), and of course readability (no special rules wrt/ 'self', it's nothing else than the first argument of the function, period).
Oh, and yes - you can use methods as functions too, it's sometimes handy for dispatching purposes !-)
