Parsing error when a class defined with metaclass keyword

[sjiang1]

The file, test3.py, being parsed:

from abc import ABCMeta, abstractmethod
class Employee(metaclass=ABCMeta):
    pass

The test case:

from redbaron import RedBaron
with open("test3.py", "r") as source_code:
    red = RedBaron(source_code.read())

Error message:

Oh wow, this is old .. yup, just hit this issue

red = RedBaron("""
class Foo(metaclass=MetaFoo): 
    pass
""")

still causes a TypeError.
