eval_type_backport
This is a tiny package providing a replacement for typing._eval_type to support newer typing features in older Python versions.
Yes, that's very specific, and yes, typing._eval_type is a protected function that you shouldn't normally be using. Really this package is specifically made for https://github.com/pydantic/pydantic/issues/7873.
Specifically, this transforms X | Y into typing.Union[X, Y]
and list[X] into typing.List[X] etc. (for all the types made generic in PEP 585)
if the original syntax is not supported in the current Python version.
