Subject: Re: [Caml-list] Specify the default hash function for a type

Polymorphic hash operates without type information, so it's not able to tell that it's hashing your record type vs. some other type with the same structure. So I would guess that what you want is not possible.

The Core team is working on a ppx extension analogous to ppx_sexp_conv and ppx_compare which generates hash functions automatically, and would make this kind of thing possible, but it's not done yet.
