Moved it to the top.

I would like to say that having an `f(RangeTy, RangeTy)` is //exactly// as 
problematic (especially if both are non-const) as having `f(int, int)` or 
`f(void*, void*)`, and should be taken care of the same way (relatedness 
heuristic, name heuristic).
The idea behind ignoring iterator-ly named things was that //"Iterators more 
often than not comes in pairs and you can't(*) do anything about it"//.

(*): Use ranges. Similarly how `draw(int x, int y)` is `draw(Point2D)` if we 
are enhancing type safety.
