I'm surprised that we're still using this as a bit of a hack in the future. In the project I'm working on, when we substantially optimise a section of code, we move the un-optimised, believed-good, version. It becomes an oracle against which the optimised version is tested on both manually and randomly generated test cases.

I'm not saying that the above solution should have been deployed at the time, but perhaps it could be moved in that direction now that we have these techniques and tools to hand.

Could such a solution work well here? Perhaps, it would be even more useful, as tests would be likely to fail if the optimisation was bad, rather than just assisting with debugging after the fact.
