> Would extending `equal' to handle hash tables be generally useful?

It would, but doing so would be very risky at this point since it would change long-standing semantics.

We could make an augmented version of `equal` but what we really want is one that works for user-defined types (see Ihor's reference to a previous discussion).

Anyway, here's an old patch I had lying around, in case we decide that we do need a shoddy equality predicate for hash tables only.
