Thanks! Added to the list, it’s suspiciously only a little bit faster than CPython 3.11 though, which probably needs more investigation… ED> Looks like CPython

Thanks! Added to the list, it’s suspiciously only a little bit faster than CPython 3.11 though, which probably needs more investigation… ED> Looks like CPython prefers using a dict as a lookup table for opcodes (which is what this implementation does), while PyPy prefers having a long series of if-statements. Hmm.

That makes sense because pypy can JIT a ladder of if/else to a compare/jump conditional each whereas a dict lookup can be an order of magnitude more complex. If they're 8bit opcodes, maybe having a list based lookup table will perform similarly on py3000 and still optimize on pypy? Or maybe https://docs.python.org/3/library/array.html https://docs.python.org/3/library/array.html rather than list.
