 From the library reference:

assert(equal(splitter("hello  world", ' '), [ "hello", "", 
"world" ]));

and

"If a range with one separator is given, the result is a range 
with two empty elements."

My problem was that if I have input like

auto word = "bla-";

it will return parts.data.length == 2, so I would have to check 
parts.data[1] != "". This is too awkward. I just want the parts 
of the word, i.e.

length == 2 // grab [0] grab [1]
length == 1 // grab [0] (no second part, as in "bla-")
length > 2 // do something else
