Not quite. Since it's a table[count], it's implemented as a hash table,
and prints out in an arbitrary order. However, if you iterate from
1 .. its length, you can pull out its elements in order. (I thought there
was a built-in that makes doing this easy, but I'm not seeing it. :-( )

The characters of the original string!
The semantics of split_all is that it splits on anything that matches
the regular expression, returning the strings between the split points
intermingled with the separators themselves. For split_all("foobar", /./),
*every* character is a separator, so the strings between split points are
empty, and the original characters show up in the separator (even) slots.
