   The latter, for sure "temporary way to have an assert_type function until the implementation in mypy"

   I had some code which was very complex in terms of generic typing and needed a way to make sure changes to the codebase didn't change the resulting typing, and at the time mypy didn't support it (and I couldn't use the other type-checking libraries).

   I'll be very happy to archive this library/repo when assert_type is something I'll be able to use in my code 😅

   Alright, noted, thank you for the answer!

   Right now, something like the following can be used:

   if TYPE_CHECKING:
       from typing_extensions import assert_type
   else:
       def assert_type(val, _):
           return val
