Explicitly heterogeneous metaprogramming with MetaHaskell

Abstract

Languages with support for metaprogramming, like MetaOCaml, offer a principled approach to code generation by guaranteeing that well-typed metaprograms produce well-typed programs. However, many problem domains where metaprogramming can fruitfully be applied require generating code in languages like C, CUDA, or assembly. Rather than resorting to add-hoc code generation techniques, these applications should be directly supported by explicitly heterogeneous metaprogramming languages.
