   This is a known problem (though there doesn't seem to be an open issue). If there are cyclic module dependencies, type inference often needs help because mypy does only a single type checking pass.

   In this particular case, you may want to rewrite cases like this:

   Constraint = scheme.Constraint
   

   into something like this:

   from .scheme import Constraint as Constraint
   

   Let me know if that works for you.

   That workaround worked for the sqlalchemy stubs; I had actually tried it before unsuccessfully, but I now suspect that was due to an unrelated problem.

   Closing as this seems like a special case of #481.
