Functional programming languages for verification tools: a comparison of Standard ML and Haskell

Abstract

We compare Haskell with Standard ML as programming languages for verification tools based on our experience developing the verification platform Truth in Haskell and the Edinburgh Concurrency Workbench (CWB) in Standard ML. We review not only technical language features but also the worlds of the languages, for example, the availability of compilers, tools, and libraries. We also discuss the merits and difficulties of comparing programming languages in this wide sense and support our view that Truth and the CWB are similar enough to justify the conclusions drawn in this paper.
