(* Binable: signatures defining generated functions for the binary protocol.
   [S, S1, etc] are the signatures satisfied by the generated code and
   [Minimal.S, Minimal.S1, etc] are the signatures that generated code uses. *)

  (**
     This function only needs implementation if [t] exposed to be a polymorphic variant.
     Despite what the type reads, this does *not* produce a function after reading;
     instead it takes the constructor tag (int) before reading and reads the rest of the
     variant [t] afterwards.
