Agreed. Do you know by which timeframe you'll know which opcodes you want to add?
I'm currently in the middle of the first part, trying to implement pickling local classes with static and class methods without creating loops. Other parts exist just like general ideas, I didn't rite code for them still. I try to do this with existing protocols, but maybe some new opcodes will be needed for efficiency. We are now at the early stage of 3.8 developing, and I think we have a lot of time.
It wouldn't deserve bumping pickle version, but if we do this already, it would be worth to add shorter versions for FRAME. Currently it uses 64-bit size, and 9 bytes is a large overhead for short pickles. 8-bit size would reduce overhead for short pickles, and 32-bit size would be enough for any practical use (larger data is not wrapped in a frame).
