In this talk, Lennart will show how to design a strongly typed interface to an external library. The external library has some rather complex, dynamically checked, types. Making a strongly typed, easy-to-use version of the API uses several Haskell type system extensions, e.g., type level strings, closed type families, kind definitions. It even uses some extensions that are not quite in ghc yet.
