For over 11 years, Standard Chartered has maintained its own proprietary compiler for a dialect of Haskell called “Mu”. In this talk we present its origins in the context of a global Financial Markets business, a rationale for the main differences between Mu and Haskell (such as strictness by default), and choices on compiler and library design, such as whole-program compilation, and serialisation of any computation for parallel execution. We conclude with some code and language extension usage statistics from our production code repository, and present a plan to bridge the gap between Mu and Haskell in the near future.
