Abstract

Plaid is a research programming language with a focus on typestate, permissions, and concurrency. Typestate describes ordering constraints on method calls to an object; Plaid incorporates typestate into both its object model and its type system. Permissions, incorporated into Plaid's type system and runtime, describe whether a reference can be aliased and whether aliases can change that reference. Permissions support static typestate checking, but they also allow Plaid's compiler to automatically parallelize Plaid code. In this paper, we describe the usability-related hypotheses that drove the design of Plaid. We describe the evidence, both informal and scientific, that inspired and (in some cases) validated these hypotheses, and reflect on our experience designing and validating the language.
格子设计中的可用性假设
Plaid是一种研究性编程语言,主要关注类型状态、权限和并发性。Typestate描述对对象的方法调用的排序约束;Plaid将类型状态合并到它的对象模型和类型系统中。权限,合并到Plaid的类型系统和运行时中,描述了引用是否可以别名,以及别名是否可以更改该引用。权限支持静态类型状态检查,但它们也允许Plaid的编译器自动并行化Plaid代码。在本文中,我们描述了驱动Plaid设计的可用性相关假设。我们描述了启发和(在某些情况下)验证这些假设的证据,包括非正式的和科学的证据,并反思了我们设计和验证语言的经验。
