-"""Contains logic for retrieving special methods.
-
-This implementation does not rely on the dot attribute access
-logic, found in ``.getattr()``. The difference between these two
-is that the dunder methods are looked with the type slots
-(you can find more about these here
-http://lucumr.pocoo.org/2014/8/16/the-python-i-would-like-to-see/)
-As such, the lookup for the special methods is actually simpler than
-the dot attribute access.
