Comment:
OK, here is my implementation. With a big fat warning about performance
considerations, to reduce the chances of inappropriate use.
In comment:16:ticket:15515 I had to undo some changes by Jeroen Demeyer to
avoid breaking compatibility for positional arguments. So it seems I'm not
the only one who would like to get rid of some positional parameters to
simplify implementations. With this tool here, we can have a proper
deprecation period before we can finally dump them.
And with the `extra` keyword I introduced, things are even simpler for
those cases. That keyword allows me to specify the names of any excess
positional parameters, which will then be included in the `**kwds` dict so
one doesn't have to mention them a second time when passing those
arguments down the line.
