Ensure unwanted names removed in class definition

How can I ensure incidental names don't end up in the class definition, with code that works on both Python 2 and Python 3? With the following class definition, the incidental names `foo` and `bar`, only needed for the list comprehension, remain in the `Parrot` namespace:: __metaclass__ = obj
