You might be interested in this thread from my multimethod library:
<https://bitbucket.org/coady/multimethod/issues/2/>. It was a feature request
for multiple dispatch to work on instance methods. I implemented a variation
where the initial self argument still contributed to the dispatch.
I think the same reasoning would apply in the single dispatch case: that it’s
not obvious the “dispatch” would occur once on the self argument to find the
method, and then again on the “first” argument. Especially since Py3 did away
with bound methods, so you can call a method through its class and explicitly
supply self as the first argument.
