If you had said "a huge speedup, on all programs", on the weak end of maybe. "Small speedup" isn't worth the obscurity. Note that Python contains no assembler now.
Its arguable which is more obscure, the x86 assembly instruction "jo" (jump if overflow), or the xor trickery in C. <wink>
I take your point, though, about there being no assembly in python now.
The place to put this sort of low-level instruction optimization is in the peepholer of your C compiler. -- David Eppstein http://www.ics.uci.edu/~eppstein/ Univ. of California, Irvine, School of Information & Computer Science
