Latest version seems to break mypy

when running mypy on my project, I get this error: Error importing plugin sqlmypy

When debugging a little bit, the problem seems to be here:

    def get_dynamic_class_hook(self, fullname: str) -> CB[DynamicClassDefContext]:
  File "/usr/lib/python3.5/typing.py", line 546, in __getitem__
    "Cannot subscript an existing Union. Use Union[u, t] instead.")
TypeError: Cannot subscript an existing Union. Use Union[u, t] instead.

I fixed this issue by adding sqlalchemy-stubs explicitly in .pre-commit-config.yaml, like this:

-   repo: https://github.com/pre-commit/mirrors-mypy
    rev: 'v0.910'
    hooks:
    - id: mypy
      additional_dependencies:
        - 'pydantic'
        - 'sqlalchemy-stubs'

I do… however, I discovered that, for whatever reason, my shell was using my global mypy. Forcing a re-hash fixed things. Sorry for the confusion!
