We have recently published (yet another) JSON Deserializer.
However I’ve always been uncomfortable with the idea of not being able to derive the deserializer from the return type, or viveversa: build the type from the fields structure.
Recently I found that PPX are kind of the macro system for OCaml. I’m wondering if there’s already a PPX based solution for JSON deser (with similar goals to Rust serde); or even if PPX is the right about it. (I’m still learning basic OCaml, so PPX are still a little ahead).
