> I tried to implement such optimization in my old https://faster-cpython.readthedocs.io/fat_python.html project. I implemented guards to de-optimize the code if a builtin is overriden. 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.
