Model Field in type annotation runtime error

[cs-cordero]

Originally posted on the gitter:

I'm coming across this issue where I'm trying to use a Field in a type annotation something like: Dict[Field, Any]

If i use mypy on this with django-stubs enabled, i get this error message:

`Missing type parameters for generic type`

so then i change it to Dict[Field[Any, Any], Any], and that fixes the problem in mypy, but at runtime, it fails:

`TypeError: 'type' object is not subscriptable`

Could you confirm whether errors goes away when you specify disallow_any_generics=False in the config file?

Currently django-stubs is incompatible with this setting, I've created issue for that https://github.com/mkurnikov/django-stubs/issues/64.

Yes, it seems the errors do go away when you specify that setting in the config file.

Closing in favor of #64
