There was a problem hiding this comment.
Chatted offline about the tradeoffs of removing REPLACE_OPCODE_IF_EVALUATES_PURE right now (thanks for the clarification @Fidget-Spinner!). For anyone else reading, this is much more valuable since this optimization applies to any LOAD_FAST not just non-immortal constants.
LGTM!
