While it appears to rhyme with the use of a lone '*' in function signatures, it would actually mean the opposite: in signatures it means "don't allow any more".
That's the usage that's out of step with the rest -- all the others can be seen as some form of wildcard.
So it's already confusing, and I don't think adding another wildcard meaning would make things any worse.
How does "stop iterating here" equate to a wildcard? We already have a "wildcard" for iterable unpacking, using the extended iterable unpacking syntax: x, y, *z = iterable which unpacks the first two items into x and y and the rest into z. This is the opposite: *stop* unpacking, so that after x and y are unpacked the process stops. I don't see how this is conceptually a wild card. -- Steve
