I think when Riccardo said "The PEPs are the worst," he meant that PEPs
do not work well as documentation for features, because it was not their
purpose. PEPs are designed to be proposals, and then summaries of
decisions. I agree with him that linking to PEPs should be for
supporting informat

But Point(x as a) already has a meaning in PEP 634; it’s a positional
argument captured in x *and* in a. (Previously spelled as Point(a := x).
The phrase ‘as a’ can be added after any pattern to *also* capture it in
‘a’. More typically used as e.g.‘Pattern(x, y) as p’, which captures the
first two
