I have added this paragraph:

    Implementations must support any comparator that provides
    both a comparison procedure and a hash function, as well
    as the comparators `eq-comparator`, `eqv-comparator`, and
    `equal-comparator`.  Implementations may support other
    comparators, possibly with some degradation of performance.

This permits an all-singing all-dancing implementation to use hash tables
if a hash function is available, trees if a comparison procedure is
available, and lists if neither is available.
