Hi, I'm new to this kind of stuff, could you please clarify this for me please? From the variable name, it is a type
already, why do we need to convert it to type()
here? Is it just your preference or there are some edge cases being handled implicitly here?

Hi, thanks for this PR!
There's a few other PRs that address the same issue, of which I think #548 would be the prime candidate to merge. That PR uses existing functionality such as utils.needs_py310
and ._typing.is_union
. If we merge #548, I think we can go ahead and close this one.
I'll leave the final decision with Tiangolo though.
This resolves the issue #533
