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.
