> FWIW the globals opcode cache handles all of this now. There's no point in specifically optimizing the builtins lookup since we optimize all global lookups for a code object that's hot enough.

So you think that even a dedicated "LEN" opcode would not be any faster? (This is getting in Paul Sokolovsky territory -- IIRC he has a variant of Python that doesn't allow overriding builtins.)
