Jack Diederich <[email protected]> added the comment:
We talked about it at sprints and the semantics are ambiguous and there are
alternatives.
Ambiguous:
def show_funcs(*args): print(args)
class A():
run = partial(1)
ob = A()
ob.run(2,3)
Should this print (self, 1, 2, 3) or (1, self, 2, 3)? And what about
partial(ob.run, 2)(3)
Alternatives: partial is a convenience function not an optimization (it doesn't
offer a speedup. So you can write a lambda or named function that has the
exact semantics you want without suffering a speed penalty.
So unless there are a lot of good use cases with obvious behavior, we should
refuse the temptation to guess and leave partial as-is.
