Yury Selivanov and Serhiy Storchaka told me that they will review
shortly the patch. I give them one more week and then I will push the

I agree that the patch is in a good shape. I reviewed first versions
of the change. I pushed some minor and obvious changes. I also asked
to revert unrelated changes.

I proposed to not try to optimize ceval.c to fetch (oparg, opval) in a
single 16-bit operation. It should be easy to implement it later, but
I prefer to focus on changing the format of the bytecode.
