Type Hinting - Constrain metaclass of typing.Type

  Optional static typing for Python

  

  Been looking into it a bit more. I think you're right, it's not supported. Turns out mypy only has very limited support for type hinting metaclasses. This page suggests it may be possible to support this with a mypy plugin, but I'm really not looking to do something that involved. Just wanting to hint an existing API :/ I suppose I could look into tweaking the API to be more hint-able, but I think I'll just accept this piece isn't perfect.
