Starting with Python 3.13, `locals()` has changed semantics when called in optimized scopes (in particular, it now always returns independent snapshots in such contexts, so that changing the values of local variables via `exec()` is being consistently ignored). In contrast, `frame.f_locals` gives read/write access to the local variables in all scopes, including optimized scopes. Replacing `locals()` with `sys._getframe().f_locals` inside an `exec()` call restores the old behavior.
