Why doesn't reverse iteration of lockstep work? It does for zip. Is this intended or is it a bug?
Lockstep is actually not a range. It overloads the opApply[1] operator to support foreach. To support foreach_reverse, it would also have to override opApplyReverse. I'd say that it's not a bug but still a valid enhancement request. BTW the upcomming release has better documentation on the differences between lockstep [2] and zip [3].
