Re: [Python-Dev] default of returning None hurts performance?

I was just wondering if a bytecode for a superinstruction of the common

6 POP_TOP 7 LOAD_CONST               0 (None) 10 RETURN_VALUE might be worth it.

I think superinstructions in general would be a good thing to experiment, as wpython showed. Direct addressing (via a pseudo register file combining locals and constants) would eliminate many bookkeeping-related opcodes in common bytecode. Regards Antoine.
