I think in the spirit of avoiding "premature optimization" and all things related, now is the time to re-inject the other part of my above-quoted posting, where I also said: """ Of course, if you have a state machine with many small states each doing a tiny bit of processing and you're still concerned over performance, you probably should be looking into Pysco or Pyrex and avoid making your code really unreadable.
