Abstract

mist is a tiny language for teaching and experimenting with refinement types, in the style of https://github.com/ucsd-progsys/liquidhaskell. We use it as a platform for experimenting with and as a demonstration of implicit refinement types as presented in the ECOOP21 paper Refinements of Futures Past: Higher-Order Specification with Implicit Refinement Types. We start with the parser and AST we use to teach our undergradute compilers class, and layer upon it a refinement type checker directly translated from the typing rules presented in that paper, which produces constraints that are solved with the liquid-fixpoint horn clause solver.
We present source code and binaries for mist in a container image that includes installations of the competing tools we compare to.
