Today I’m happy (and a little trepidatious) to announce the next
version of PEP 622, Pattern Matching.
Thank you very much to everyone who has been working on this, it is much
appreciated. I have one suggestion for the text: could the section on
Capture Patterns emphasise that only simple (i.e not dotted) names are
capture patterns? The simplified grammar is (fairly) clear and the
later section on Constant Value Patterns should make it obvious, but
somehow when reading version 1 I still managed to miss it. I was quite
surprised when it was pointed out that
case (point.x, point.y):
wasn't going to do what I expected!
(PS: I'm still pushing for an "else" clause, and I can see arguments for
it going at either indentation level. Since putting the clause at the
wrong level would be a syntax error, I don't see it being a particularly
big issue where it goes.)
