The predicate is passed to $(REF binaryFun, std,functional), and can either accept
a string, or any callable that can be executed via $(D pred(element, s)).
If the empty range is given, the result is a range with one empty
element. If a range with one separator is given, the result is a range
with two empty elements.
If the empty range is given, the result is an empty range. If a range with

If splitting a string on whitespace and token compression is desired,
consider using $(D splitter) without specifying a separator (see fourth overload
