I would say that the only problem with this terminology is that it would be
good to think of a word to replace "keyword-only" (positionless?).
I disagree completely. I think keyword-only is the right terminology to
use for arguments which can only be passed by keyword. It is *positional*
that is questionable, since named positional arguments can be given by
keyword.
I would like to see error messages reserve the terms:
1) "positional" for explicitly positional-only parameters;
2) "keyword" for explicitly keyword-only parameters;
(I don't mind whether or not they use "-only" as a suffix)
For normal, named-positional-or-keyword arguments, just use an unqualified
"argument".
