loops:reusingiteratorvariables
I totally agree with your explanation, and the part that I am being pouty
about is: "Why isn't the variable's scope confined to the loop?"
a la:
for (var i:int = 0; i < limit; i ++) { // variable is instantiated
// scope of variable
} // variable is discarded
instead of it being what several of you have described.
