If you use switch(enum) you should not implement default: You will get a helpful warning when a value is not implemented. This is useful when new values will be added to the enum. You don't forget to handle the new value because of the warning. When a value doesn't need to be handle, add it at the end of the switch with a break.

overriding self might seem strange, but it ensure that you cannot accidentally use the strong self.
