Is there a clever way that I can discard all the extra null
strings in the resultant string array?
Easiest way is to use [`filter`][1]. Here's an example:
```d
import std.algorithm: splitter, filter;
import std.uni: isWhite; // or use std.ascii for non-unicode input
import std.array: array;
import std.stdio: writeln;
string exampleText =
"Hello 123-456-ABC x\ny\tz\r\nwvu goodbye";
void main()
{
string[] tokens = exampleText
.splitter!isWhite
.filter!(t => t.length > 0)
.array;
writeln("tokens = ", tokens);
}
```
I've also used the lazily-evaluated [`splitter`][2] instead of
the eagerly-evaluated `split`, to avoid allocating a temporary
array unnecessarily.
