Hm.. can someone explain whats going on?
Let's try again. I'm not sure the full explanation, but likely
involves two separate template overloads being instantiated, each
with a separate definition of the return type.
* "a.b.c".splitter('.') - This overload:
https://github.com/dlang/phobos/blob/master/std/algorithm/iteration.d#L3696-L3703
* "a.b.c".splitter(".") - This overload:
https://github.com/dlang/phobos/blob/master/std/algorithm/iteration.d#L3973-L3982
But why one supports dropBack and the other doesn't I don't know.
