I don't think all attempts are failed. Note that current CPython includes some optimization already. If they are all failed, we must remove them to make compiler simple. And I think there are some potential optimization if we can limit some debugging/introspecting features, like some C variables are "optimzed away" in gdb when we use -O option. Regards,
