Well, the output requires O(n) heap by nature of
the result..

Good question. one reason is that it's hard to do better
in a specification: you can't very well say 'this takes
1 second' :-)

However, perhaps you can say something for small n.

Usually this is a QOI issue. QOI = Quality of Implementation.
Meaning "not an issue for standardisation". QOI is important
of course -- we use Ocaml because of its high performance.
