Title: Metaprogramming Haskell, The Racket Way

Author: Alexis King

Abstract: Racket programmers believe programs are best expressed in domain-specific languages, but most DSLs suffer from impoverished programming models and poor tooling support. To remedy this, Racket provides an expressive macro system that helps domain-specific languages compose and work together. The hundreds of little languages available to the Racket programmer are evidence of the macro system’s success, but currently, almost none of them are statically typed. In this talk, I’ll take a look at what makes that so hard by exploring what makes the Racket macro system special, and I’ll present an approach that overcomes some of those obstacles to support a full-fledged Haskell dialect within a macro-enabled language.
