Fix filter() usage due to python 3 compability
Fix filter() usage due to python 3 compability

Built-in method filter() returns a list in Python 2.x [1], but it
returns an iterator in Python 3.x [2]. To remove the difference (and
make code more readable, also), we use list comprehension instead of filer().

## Code Before:

import gc

    """A String that can have arbitrary attributes
    """

    pass


def _find_objects(t):
    """Find Objects in the GC State

    This horribly hackish method locates objects of a

    return filter(lambda o: isinstance(o, t), gc.get_objects())
