This is still deviating from the point Phanx and I were making. Phanx is stating as a general rule that locals should stay in the tightest scope possible. My posts state that like most rules, there are some exceptions over the argument whether locals should stay in or out of loops.

Among these is the point that when dealing with constants or CPU-intensive calculations that don't change in the loop, you're best left upvaluing them instead of having the loop reinitialize the variable with the same value multiple times.
