I was thinking about making D ranges be to D arrays as C++ iterators are to C++ pointers: r[0] is head and r[$ - 1] is toe. But that has problems, since you can't make an infinite range, since you can't say that r[0] is legal while r[$ - 1] is not. (D also doesn't allow overloading $, an irritating limitation, but one that could be fixed in order to implement such a paradigm.)
IIRC, Python uses negative indices to iterate from the end. Or is this entirely not what is under discussion?
