Also i am trying to fix all failing tests

Edit :

Initial observations conclude that typing doesn't have ForwardRef in python 3.6

So do we keep the import from pydantic.typing? ( mypy is not happy with this )

Or do we continue with a import from python typing? ( see : https://github.com/python/mypy/issues/8301 )

---

Edit 2 :

Changing python version to 3.7 fixes the mypy issue

MyPy ( logs ) :

(django-ninja) PS C:\Users\Asus\Desktop\test\django-ninja> mypy ninja
Success: no issues found in 45 source files

FastApi Creator Tiangolo's comment confirmed it

[baseplate-admin]

Changing the MyPy version to target python 3.7 fixes the codestyle issue.

But we have to drop python 3.6 support entirely

( note that pydantic is 3.7+ )

Is this acceptable to you ?
