Paradise: a two-stage DSL embedded in Haskell

We have implemented a two-stage language, Paradise, for building reusable components which are used to price financial products. Paradise is embedded in Haskell and makes heavy use of type-class based overloading, allowing the second stage to be compiled into a variety of backend platforms. Paradise has enabled us to begin moving away from implementation directly in monolithic Excel spreadsheets and towards a more modular and retargetable approach.
