Agreed. But with the right tools I believe that Psyco might be worth it in the work/advantage ratio. If my understanding is correct, it's the only optimization tool that "understands" python types and optimizes your code for the types you use, in the Python Way (exceptions after rather than checks before for the rare cases). And it's the only one that is easy to laser-focus from inside Python. This gives it a niche, even if all the other magic being discussed is performed. But as you point out, that niche is dependent on having dead-easy Python profiling tools.
