I dig it. 'as' primes my brain to something going into a scoped context.

  It’s fine. Python just introduced expression assignment. Why not use that? match subject case [first := _, rest := _] return [rest, first]

    Note that the original PEP622 relied on ":=" initially, but they found some corner case with it (apparently, operator precedence related) and switched to "as" in PEP634.

    That works too but I guess I am still getting used to the walrus operator. What really bugs me about this PEP is they are going through all this effort to introduce match but they don't have match assignments, which is personally one of my favorite things about match.
