Automatically generating the dynamic semantics of gradually typed languages

Abstract

Many language designers have adopted gradual typing. However, there remains open questions regarding how to gradualize languages. Cimini and Siek (2016) created a methodology and algorithm to automatically generate the type system of a gradually typed language from a fully static version of the language. In this paper, we address the next challenge of how to automatically generate the dynamic semantics of gradually typed languages. Such languages typically use an intermediate language with explicit casts.
