This is probably caused because I used emacs's fill-paragraph (alt+q)
command, after some changes. If this is against policy, I could change
the additions in such a way as to cause minor differences, however I
believe that the benefit of that ends immediately after review.

Good point, both changed.

I moved the error up, though I personally tend to believe it doesn't
even need to be an error. There is no technical reason not to allow it.
All the user needs to do is make sure that the combination of named
parameters and the positional ones together are complete and not
overlapping. This is also in line with calling functions, where mixing
named and positional is allowed, as long as the positional arguments are
first. Personally I have no opinion what is best, include the feature or
give an error, and I removed the possibility during the previous commitfest.

This is removed, also the -- START ADDITIONAL TESTS, though I kept the
tests between those to comments.

Same here.

The new patch is attached.
