In an ideal world, the speed of these two codes should be the same, of course i'm "assuming" that most competent language designers would optimise the slower version.

Even if the bytecode can't be optimized on the current run, it CAN be optimized by updating the .pyo file for future runs without degrading current (or future) runtime performance.
