No RC yet, just beta releases, but we can already start setting stuff up.

3.13 release schedule: https://peps.python.org/pep-0719/#schedule

…on 3.13) (#3272)

The `_partialmethod` attribute of methods wrapped with `partialmethod()`
was renamed to `__partialmethod__` in CPython 3.13:
python/cpython#16600
…3271)

Starting from Python 3.13, `frame.f_locals` is not `dict` anymore, but
`FrameLocalsProxy`, that cannot be copied using `copy.copy()`. In Python
3.13 and later, it should be copied using a method `.copy()`. The new way
of copying works the same as the old one for versions of Python prior to
3.13, according to the documentation (both copying methods produce a
shallow copy).

Since Python 3.13, `FrameLocalsProxy` skips items of `locals()` that have
non-`str` keys; this is a CPython implementation detail, so we hence
disable `test_non_string_variables` test on Python 3.13.

Do these allow-prereleases: true have any affect on non-3.13 tests? I would be hesitant to merge this if so

Edit: Just noticed the "Do not merge" label, is that still accurate?

^ Basically, frame.f_locals is no longer a dict in 3.13

Will double check this.

@szokeasaurusrex allow-prereleases will only kick in if the specified Python version is not generally available (all older Python versions are, so no effect there), see here.
