摘要

Grace是一种新的渐进的、结构类型的面向对象程序设计语言。现有语言的正式模型为声明类型稳健性提供了严格的基础,因此我们开始着手创建Grace子集的模型。虽然很多关于对象的正式文献都使用了结构类型,但是流行的现代语言(如轻量级Java)的模型不得不使用名义类型来匹配它们所建模的语言。与此相反,我们提出了Tinygrace: Grace的一个子集,具有结构类型系统,与FJ的特征奇偶性,以及伴随的稳健性证明。

Tinygrace: A Simple, Safe, and Structurally Typed Language
Grace is a new gradually, structurally typed object-oriented programming language. Formal models of existing languages provide a rigorous base for claiming type soundness, so we have set about creating a model of a subset of Grace. While much of the formal literature of objects has used structural typing, models of popular modern languages such as Featherweight Java have had to use nominal typing to match the language they are modelling. In contrast to this, we present Tinygrace: a subset of Grace with a structural type system, feature-parity with FJ, and an accompanying proof of soundness.
