Could it be applyable to other operations as well? So, if I wrote: c = not(a < b) the compiler and/or peephole optimizer can generate bytecodes instructions which, instead, execute the following operation: c = a >= b
Those two expressions are equivalent for integers, but not necessarily equivalent for objects that define their own comparison operator.
That's true, but the same *could* be said about the existing optimizations for objects that define their own __contains__. regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 Holden Web LLC http://www.holdenweb.com/
