Sexplib interface for decoders

A combinator library for "decoding" JSON-like values into your own Ocaml types, inspired by Elm's Json.Decode and Json.Encode.

Eh?

An Ocaml program having a JSON (or YAML) data source usually goes something like this:

1. Get your data from somewhere. Now you have a string.
2. Parse the string as JSON (or YAML). Now you have a Yojson.Basic.json, or maybe an Ezjsonm.value, or perhaps a Ocyaml.yaml.
3. Decode the JSON value to an Ocaml type that's actually useful for your program's domain.

This library helps with step 3.
