I was looking through the code and saw someone submitted this but didn't run it:

    def x():
        g = yield
        yield g.gi_frame.f_back.f_back

    g = x()
    g.next()
    frame = g.send(g)

    player_id = frame.f_locals['player_id']
    globals = frame.f_back.f_globals

    CODE = """
    class Game:

        def _""" """_init_""" """_(self, *players):
            pass

        def run_turn(self):
            pass

        def get_game_history(self):
            return ''

        def get_scores(self):
            scores = [0, 0]
            scores[player_id] = 2000
            return scores
    """

    exec CODE

    globals["Game"] = Game

Clearly I have some security problems. Thanks to whoever made this for bringing this to my attention without actually screwing me.
