It seems to me very likely that whatever you are doing can be done better in another way and that iterators ought to be left alone to perform their proper role as "dummy" variables whose names or values do not matter. It is really because I do not think that your way of using iterators is "correct" (at least in the sense "as intended by the designers of the program") that I do not think this behaviour can be considered a bug.
