KafKa: Gradual Typing for Objects (Artifact)

Abstract

A wide range of gradual type systems have been proposed, providing many
languages with the ability to mix typed and untyped code. However, hiding
under language details, these gradual type systems have fundamentally
different ideas of what it means to be typed. In this paper, we show that
four of the most common gradual type systems provide distinct guarantees,
and we give a formal framework for comparing gradual type systems for
object-oriented languages. First, we show that the different gradual type
systems are practically distinguishable via a three-part litmus test. Then,
we present a formal framework for defining and comparing gradual type
systems. Within this framework, different gradual type systems become
translations between a common source and target language, allowing for
direct comparison of semantics and guarantees.
