D's dynamic arrays are really quite weird in that they're sort of containers
and sort of not. So, pretty much nothing is ever going to act quite like a
dynamic array. But when dynamic arrays are used as ranges, their semantics
definitely are not that of containers. Having a container which is treated
as a range is just begging for trouble, and I would strongly advise against
attempting it. When it comes to containers, ranges are intended to be a view
into a container, just like an iterator is intended to be a pointer into a
container. Neither ranges are iterators are intended to _be_ containers.
Treating a container as a range is going to get you weird behavior like
foreach removing every element from the container.
