The term reference in D is a bit overloaded. The whole point of RefRange is to have the original range affected by everything that happens to the new range as if it were the original range - which is what happens with ref (which is not rebindable) except that ref only works on parameters and return types. So, yes, it is similar to a C++ reference. It's not trying to be a pointer, which is more like what a class reference is. - Jonathan M Davis
