[New-bugs-announce] [issue44341] Conflict between re.match and match keyword

[Finn Mason]

New submission from Finn Mason <finnjavier08 at gmail.com>:

>>> import re
>>> re.match('str', 'str').group()
'str'
>>> match 'str':
...     case 'str':
...         print('match!')
...
match!
>>> from re import match
>>> match
<function re.match ...>

As the above example demonstrates, while re.match doesn't raise an error despite having a keyword name, importing re.match directly into __main__ replaces the keyword with the function. The obvious solution is to rename re.match, but this would break many, many pieces of code.
