If I have a range like this, how do you find its last item using Phobos?
A simple way is to use seq.array.back, but this wastes memory. Another
simple way is to use a foreach loop keeping the last seen. But do you
know if there is a function to do in Phobos? And if such function is not
present (walkBack? backWalk?) is it a good idea to add it to Phobos?
Interesting problem. Given that it is a forward range, a zip between it
and a saved copy that is advanced by one may work.
