I think what you are suggesting is sufficiently | cleaver that the average Python coder may not have thought of it. | | # small cut | | And the "from __builtin__ import *" additionally imposes a startup | cost and memory cost (at least a word per builtin, I would guess). I suppose that if someone decided to use "from __builtin__ import *" to avoid double lookup, this person *knows* what builtins should be optmized, and therefore could use import specific builtins "from __builtin__ import len, max" avoiding a startup/memory penalty. Otherwise, the startup/memory penalty might be non-issues. cheers, Rod Senra
