You mean a version of PyPy that runs super fast as regular PyPy but that can also handle introspection? If it were that easy, why doesn't PyPy have that in place already? I think it's a lot harder than it sounds.

a version of pypy that handles enough introspection for logging to work, not e.g. dynamically modifying locals. it's not done because i have more important things to do in my free time essentially. as i said, if i can justify a week of paid time to do that, i would make logging fast.
