PS: Holy moly! Computed gotos totally put my Python on fire! The feature increases the minimum run-time by approx. 25% and the average run-time by approx. 40% on my Ubuntu 8.10 box (AMD64, Intel(R) Core(TM)2 CPU T7600 @ 2.33GHz). -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
