X Title: GH-98831: Implement basic cache effects by gvanrossum · Pull Request #99313 · python/cpython

Description: I apologize for the mess that generate_cases.py has become. I promise I will clean it up in the next PR. This PR is a big step forwards though -- it supports cache effects and implements those for the BINARY_OP family (with one exception -- the "hemi-super-instruction" BINARY_OP_INPLACE_ADD_UNICODE). Check the generated code for the effects. PS. Merge conflicts for Python/bytecodes.c are quite painful, it seems there are several cooks in this kitchen. :-) Issue: gh-98831
