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.

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."
