Sorry for off-topic, but what is the reason of using hasattr(obj, '__call__') instead of just callable(obj)? The latter is much faster and looks better IMO.

I don't know. Maybe for compatibility with Python 3.0 and 3.1.

Do you mind to open an issue for this @ilevkivskyi? If ignore Python 3.0 and 3.1, callable(obj) looks better replacement.
