Wow thanks for the pointer! This is great. I want to move more stuff to compile-time, like name resolution, and moving some control flow to compile time is something I've also wondered about.

I watched a few talks [1] about how C++ exception handling works, and they try to avoid branches/setup blocks in the "happy path". It works a little like longjmp() in C, where you just set the instruction pointer say three function calls down in the stack. But then you have to look up all the exception handlers to run in precomputed tables (which doesn't happen in C). So I wonder if something like that would speed up (my subset of) Python, since exceptions are quite common.
