Oh, I did not invent this class, it is in the test script for pattern matching : https://github.com/python/cpython/blob/6948964ecf94e858448dd28eea634317226d2913/Lib/test/test_patma.py#L1932 With this class, [x, *_, y] matches, but not [x, *w, y] : this is what made me create this issue. Maybe it would be a good idea to change this class in test_patma.py ? OTOH, if the current implementation remains the same, why does the PEP insist on subjects having a len() ? Could sequence patterns match a wider range of subjects that can be unpacked ? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44741> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
