WeakSet should be cared specially. Maybe, ABCMeta can be optimized first. Currently, ABCMeta use three WeakSets. But it can be delayed until register or issubclass is called. So even if WeakSet is implemented in Python, I think ABCMeta can be much faster.

Simple uses of WeakSet can probably be replaced with regular sets + weakref callbacks. As long as you are not doing one of the delicate things (such as iterate), it should be fine.

Antoine.
