For example, Thanks for the quick tutorial; that explains a lot. It also brings the relative time from 300:6 to 1:13. Of course, that leaves me with the question of why changing "==" it "is" in one function raised the per-call time of another (unchanged) function from 6 microseconds to 13 microseconds. But that's for another day. Cheers, Justin -- Justin C.
