TypeError when parsing file with: from __future__ import (...) followed by __metaclass__ = type

[nathanielce24]

libcst.parse_module() raises an internal TypeError when parsing a Python file that contains both:

from __future__ import (absolute_import, division, print_function) (parenthesized import)
__metaclass__ = type on the immediately following line

Reproduce With:

import libcst as cst
source = """\
from __future__ import (absolute_import, division, print_function)
__metaclass__ = type
"""
cst.parse_module(source)   # raises TypeError
