And then you can't use the idioms that the parent poster so desires, and
you revert to using similar, and apparently even slightly more
cumbersome, programming idioms as you would to manage strings in OCaml.
That was the whole point of bringing up the Shootout benchmarks.  From
the code it appears they used strings as list-of-Char, allowing the kind
of pattern matching and other manipulations the parent poster talks
about.
