error when using unicode_literals and TypeVar

[euresti]

from __future__ import unicode_literals
from typing import TypeVar

_T = TypeVar("_T")

Yields:

example.py:4: error: TypeVar() expects a string literal as first argument
example.py:4: error: "object" not callable

FWIW this is only Python 2. I suspect it's easy to fix. A simpler test case would be:

from typing import TypeVar
T = TypeVar(u'T')
