Thank you for giving an actual scenario explaining how confusion could
occur. Personally I think it's a very unlikely edge case (particularly
someone comparing argument order to their memory), and someone falsely
thinking that correct code is buggy is not a major problem anyway.
I propose using two asterisks instead of one as the magical argument
separator. `**` is more closely associated with keyword arguments,
it's harder to visually miss, and it avoids the problem mentioned
[here](https://mail.python.org/archives/list/python-ideas@python.org/message/XFZ5VH5DKIFJ423FKCTHXPHDONAO3DFI/)
which I think was a valid point. So a call would look like:
function(**, dunder, invert, private, meta, ignorecase)
In that case, would you also allow `**kwargs` unpacking to serve as a
separator? That is:
function(**kwargs, dunder, invert, private, meta, ignorecase)
Currently this is a SyntaxError. I think it would fit the symmetry with
respect to `def func(*args, bar)` vs. `def func(*, bar)`; whether or not
there is something to unpack, what follows after it remains unaffected.
