summary

HasChor is a Haskell library that encodes choreographies as a monad and compiles them to per-node programs via endpoint projection implemented with freer monads. It supports higher-order choreographies and location-polymorphism, lets local code run in IO, and demonstrates a working replicated in-memory key-value store; the implementation is concise (paper claims the projection boils down to a few interpreter clauses) and users report successfully building real projects with it.
