We present a library for generic programming in OCaml, adapting some techniques borrowed from other functional languages. The library makes use of three recent additions to OCaml: generalised abstract datatypes are essential to reflect types, extensible variants allow this reflection to be open for new additions, and extension points (PPX) provide syntactic sugar and generate boiler plate code that simplify the use of the library. The building blocks of the library can be used to support many approaches to generic programming through the concept of view. We present an application of the library to provide type-safe alternatives to OCaml's unsafe deserialization and unsafe type-cast.
