Vote for A. As far as I'm concerned, all these foo are equally
callable and equally take one parameter named a:
def foo1(a): pass
def foo(self, a): pass
def __call__(self, a): pass
def two_arg(b, a): pass
foo4=lambda a: two_arg(0, a)
If I call them as fooN(), fooN(1), and fooN(1,2), the middle one works
and the other two throw exceptions, ergo they are one-argument
functions. The fact that two of them happen to be bound methods is an
implementation detail; it's just a form of currying, which foo4
happens also to be (in that C.foo takes two args, C().foo takes one).
