I'm not sure what you mean by "immediates", but I don't think so. For
the C compiler to do an optimization like we're talking about, you
have to give it the entire expression in C for it to compile. From
the POV of the C compiler, C-Python never does more than one FP
operation at a time when evaluating Python bytecode, and there aren't
any intemediate values to store.

No, but the C compiler has no way of knowing what the Python
