Right, algorithm or control flow optimization should be located in an
earlier project stage, not in compilation. It also smells like the dream
of automated "proof of correctness", whose basics I learned 50 years ago
but never found usable results yet. How shall a tool suggest other
algorithm(s) without knowing (having determined - how?!) about the goals
of a piece of code?
