摘要

本文介绍了一种基于Erlang编程语言的软类型系统。该系统基于两个概念;确定表达式和其他结构的可能值的上限近似值的(前向)数据流分析,以及允许程序员指定模块接口的规范语言。我们将研究编程语言Erlang,并指出该语言难以输入的各个方面。我们给出了将软打字系统应用于一些已编写的程序的实验结果。

A soft-typing system for Erlang
This paper presents a soft-typing system for the programming language Erlang. The system is based on two concepts; a (forward) data flow analysis that determines upper approximations of the possible values of expressions and other constructs, and a specification language that allows the programmer to specify the interface of a module. We examine the programming language Erlang and point to various aspects of the language that make it hard to type. We present experimental result of applying the soft-typing system to some previously written programs.
