       it expects the seeded hash function to be called [seeded_hash]. This will
       reduce the amount of boilerplate in the long run, but in the transitionary
       period it increases it instead: we need to expose both [hash] and
       [seeded_hash] to be compatible with both versions of the compiler.

       Depending on which OCaml compiler (4 or 5) is used, either of the hashing
       function ([hash] or [seeded_hash]) is used. The other function is unused.
       Thus we also need to suppress the associated warning. *)
