FWIW, this is a Python implementation of a single-dispatch decorator for
methods that I wrote from looking at the stdlib, and that I have used
successfully in some projects:

from functools import singledispatchfrom functools import update_wrapper
def singledispatch_method(method):
    dispatcher = singledispatch(method)

    def wrapper(*args, **kw):
        return dispatcher.dispatch(args[1].__class__)(*args, **kw)

    wrapper.register = dispatcher.register
    update_wrapper(wrapper, method)
    return wrapper
