multimethod and inheritance

[hokkwan]

Hi all,

I was wondering if multimethod supports usage with inheritance as exemplified below.
If not supported, what are your thoughts on such functionality? And could such functionality be added?

import multimethod

class A():
    @multimethod.multimethod
    def echo(self, i):
        print("A: fallback")

class B(A):
    @multimethod.multimethod
    def echo(self, i: int):
        print("B1: int")

b = B()
b.echo(1)
b.echo("1")  # expected to fallback to A.echo

nvm, discussion can be closed, the solution was given in issue #22.
Although it would be more user friendly, if inheritance can be supported directly with multimethod instead of register.

import multimethod

class A():
    @multimethod.multimethod
    def echo(self, i):
        print("A: fallback")

class B(A):
    @A.echo.register
    def echo(self, i: int):
        print("B1: int")
