PEP 601: "Forbid return/break/continue breaking out of finally" https://www.python.org/dev/peps/pep-0601/ Abstract This PEP proposes to forbid return, break and continue statements within a finally suite where they would break out of the finally. Their use in such a location silently cancels any active exception being raised through the finally, leading to unclear code and possible bugs. Continue is currently not supported in a finally in Python 3.7 (due to implementation issues) and the proposal is to not add support for it in Python 3.8. For return and break the proposal is to deprecate their use in Python 3.9, emit a compilation warning in Python 3.10 and then forbid their use after that. Victor I can't make sense of this sentence in the PEP, I suspect there is a typo in it: "Since this is the removal of a feature teaching users will be one by the raising of a SyntaxError if/when the forbidden feature is used."

A comma after the first "feature" would also help in parsing the sentence. > ___ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/I3KSYGOCNFBXL2P7H2DQDPISZDZZGRXI/
