My motivation to add the slot wasn't the performance: it's just not
possible to have a class-level __getitem__ on types defined in C. The
only way is to define a base class in C and then extend it in
pure-Python.  This isn't too hard usually, though.

What are problems? How this differs from __sizeof__ and __getstate__?
