See http://dlang.org/phobos/std_algorithm.html#splitter
I would expect these functions to exist:
auto getHead(C)(C[] s, C[] delim, ref C[] tail);
auto getHead(C)(C[] s, C[] delim);
auto getTail(C)(C[] s, C[] delim);
As head is simply splitter(..)[0] and tail splitter(...)[1..$], extra
functions could be implemented much like this
@property T head(T[] arr) { return arr.front; }
@property T[] tail(T[] arr) { return arr[1..$]; }
..and UFCS takes care of the rest:
auto fields = splitter(...);
auto head = fields.head;
auto tail = fields.tail;
