The built-in lib2to3 does not support pattern matching (Python 3.10+): https://docs.python.org/3.11/library/2to3.html#module-lib2to3 The [black][] project managed to get some level of parsing support for `match` out of their modified version `blib2to3`, see: 1. psf/black#2242 2. psf/black#2586 [black]: https://github.com/psf/black This change adds `black` as a dependency and switches to using `blib2to3` to parse. Tests pass, but that's all that's been attempted thus far.

Thanks a lot for this @nrser 🙌 I hope I can take a closer look later this week.

The black project managed to get some level of parsing support for
matchout of their modified versionblib2to3, see:This change adds
blackas a dependency and switches to usingblib2to3to parse.Tests pass, and I am currently using it on an actual project of moderate complexity, but this is a significant change to core functionality... caution is advised. It seems like
blib2to3itself is a bit of hack/stop-gap, and that's not counting my hasty integration withdocspec-python.However, for users now in a broken state due to
matchsyntax in their source files this may be worth a shot.
