I find it very useful as well, but according to Andrei, v2 will get rid
of class-based ranges, and if those are wanted we should use a struct
wrapper instead.

In any case, if struct wrappers are the way to go, then we better have a
standard way of constructing them.  It just won't be the same thing as
std.range.interfaces.
