Ulrich Eckhardt added the comment: There is at least one thing that is missing in the patch, it lacks the necessary tests. The partialbug.py demonstrates the issue, it could be used as a base. However, even then, there is still one thing that is problematic: The fact that partial() returns som

Jack Diederich 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

Alexander Belopolsky added the comment: Christophe, It looks like your patch goes out of its way to avoid creating nested partials. This is a worthwhile goal and I think it should be done in partial_new so that partial(partial(f, x), y) returns partial(f, x, y). If fact, I was surprised to

Calvin Spealman <[EMAIL PROTECTED]> added the comment: I don't think this is any kind of bug, it is simply a product of only function objects being decorated automatically as methods. Your python version works because it is, in fact, a function. _functools.partial objects are not functions, bu
