Depends what you mean by "optimum".
Chances are that either the direct version or the reverse
version is significantly *faster* than the approaches using zip
or zipwith. The direct version never allocates a word it doesn't
want to keep, so it's the kindest to the garbage collector too.
The cost is in development time and maintenance time.
