Pytest has some non-critical (and kinda terrifying) testing code like this (paraphrasing):
backlocals = sys._getframe(1).f_locals
eval(..., backlocals, ...)
which started failing in Python 3.13 beta with “TypeError: globals must be a real dict; try eval(expr, {}, mapping)”.
I am changing this to backlocals = dict(sys._getframe(1).f_locals), just wanted to leave a note in case this was somehow not intended.
