Support for type hints via mypy plugins?

Hi,

PyCharm can use stub files for type-hinting libraries. But I could not find any documentation on how to use mypy plugins in PyCharm. Is this possible?

I am asking since I want to type-hint a library that makes extensive use of meta-classes and dynamic programming. Using just stub files isn't going to cut it in this case I'm afraid.

(On a side note, PyCharm seems to use something similar to the SQLAlchemy mypy plugin under the hood, since it's autocompletion for SQLAlchemy go beyond what's possible with just stub files.)
