Proof assistants can help check proofs, but their learning curve is too steep to use in most classes, and is a barrier to researchers too. In this paper we present SASyLF, an LF-based proof assistant specialized to checking theorems about programming languages and logics. SASyLF has a simple design philosophy: language and logic syntax, semantics, and meta-theory… CONTINUE READING
