I think "tokens" is a range. I didn't read much about it, but
I figured out that there's no particular way to know the
number of elements in a range, or how can you know the
elements order and the length of the range?
In this case, the only way is to convert the range to an array,
using [`std.array.array`][1]:
```d
import std.array: array;
// ...
string[] tokens = input
.splitter!(c => delimiters.canFind(c))
.filter!(not!empty)
.array;
```

This is the first program using "d_strtok":

This is the "dcollect" module:
