After this pull:
https://github.com/D-Programming-Language/phobos/pull/1502

This program:

void main() {
    import std.string, std.stdio;
    auto r = split("a test", "");
    pragma(msg, typeof(r));
    r.writeln;
}

Gives:

string[]
["a", " ", "t", "e", "s", "t"]


And this program:

void main() {
    import std.algorithm, std.stdio;
    auto r = splitter("a test", "");
    r.writeln;
}

Gives the same output:

["a", " ", "t", "e", "s", "t"]



It's different from what Python does:

>>> "a test".split("")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: empty separator


But it's much better than an infinite loop, it can be often useful, and I think
it's acceptable, so I close down the issue.
