Hello: I agree with Steven D'Aprano. Here is an example:

class A(object): def __init__(self, value): self.value = value def add(self, other): return self.value + other.value __magic_method__ = {'+':add}

a1 = A(1) a2 = A(2)

We only need a macro expand a1 + a2 to a1.__magic__method__['+'](a, b)

the later can be execute on Python.
