Eric V. Smith <[email protected]> added the comment:
Looking at PEP 634, the obvious way to add support for this is to have the
re.Match object specify Py_TPFLAGS_MAPPING. But I tried that, and then I get
this error when using an re.Match object in a match statement:
case {'one': x, 'two': y}:
^^^^^^^^^^^^^^^^^^^^
TypeError: object of type 're.Match' has no len()
Add len() to re.Match objects was rejected when __getitem__ was added to
re.Match, in issue 24454.
I haven't explored other ways to support re.Match objects in the match
statement.
