Most runtime type checking modules I am aware of support

  from __future__ import annotations

E.g., typeguard, Pydantic, beartype, among others.

they "support" it, but many things will break, for the simple reason that there is absolutely no way to resolve certain types at runtime. In fact the main reason why it's a future is because the pydantic people complained that it broke stuff.

When I had complained earlier, Guido didn't give 2 shits, although it broke typedload, a library I wrote that is very similar to pydantic, when pydantic didn't exist.

So I know what I am saying
