Pytest has some non-critical (and kinda terrifying) [testing code](https://github.com/pytest-dev/pytest/blob/fdf3aa3fc35ee6d336eafef5016f308b5e57bddb/src/_pytest/pytester.py#L288-L298) like this (paraphrasing):

```py
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.
