Serhiy Storchaka added the comment: Thank you for your examples Raymond, but they don't directly related to this issue, implementing support of var-positional and var-keyword parameters. I believe that it is possible to solve it, and the solution is complex, but is not extremal hard. I'm

Raymond Hettinger added the comment: In case it is helpful, here's my list of examples where the AC and existing signature objects are insufficiently expressive: type(obj) type(name, bases, mapping) two different signatures depending on type range(stop) range(start, stop) range(start,

Serhiy Storchaka added the comment: I think at first step we can support var-positional parameter only when there are no other positional parameters, and var-keyword parameter only when there are no other keyword parameters. So print, max and dict.update will be supported, but

Nick Coghlan added the comment: Yes, I agree we should follow the Python level semantics, and only capture the excess positional arguments. For the record, the four builtins I flagged as needing this in order to add introspection information: __build_class__ - 2 positional only args,

Larry Hastings added the comment: So, let's think about this for a minute. What's the API that we *want* here? If your function has the signature (a, b, c=20, *args) and you call it with (1, 2, 3, 4, 5) should args be (4, 5), or (1, 2, 3, 4, 5)? I assert that the impl function should

[issue20291] Argument Clinic should understand *args and **kwargs parameters

New submission from Larry Hastings: Argument Clinic currently prevents the impl function from ever seeing the args tuple or the kwargs dict. There should be a way to ask it to pass those values in to the impl function. -- assignee: larry messages: 208380 nosy: larry, meador.inge
