For a project, I've created something that generated toHash,
opCmp, opEquals and toString methods for a variety of structs. I
needed it to work with tagged unions, so you could declare a
special method that indicated which fields to
hash/compare/stringize.

The code may be more complicated than currently necessary, since
it was initially written for D1.
