چکیده

This paper introduces a new type system designed for safe systems programming. The type system features a new mutability model that combines unboxed types with a consistent typing of mutability. The type system is provably sound, supports polymorphism, and eliminates the need for alias analysis to determine the immutability of a location. A sound and complete type inference algorithm for this system is presented.

Non-standard type inference for functional programs

We propose a general framework for “non-standard type inference based” static analyses of typed functional programs and study inference systems (with and without conjunction) for strictness, totality, and dead-code analyses. A key feature of our framework is that it provides a foundation of the program analyses which is based directly on the operational semantics of the programming language con...

A Syntactic Approach to Type Soundness

We present a new approach to proving type soundness for Hindley/Milner-style polymorphic type systems. The keys to our approach are (1) an adaptation of subject reduction theorems from combinatory logic to programming languages, and (2) the use of rewriting techniques for the speciication of the language semantics. The approach easily extends from polymorphic functional languages to imperative ...

Coercions in a polymorphic type system

The idea of coercive subtyping, a theory of abbreviation for dependent type theories, is incorporated into the polymorphic type system in functional programming languages. The traditional type system with let-polymorphism is extended with argument coercions and function coercions, and a corresponding type inference algorithm is presented and proved to be sound and complete.

Complete type inference in functional programming

Dynamically typed functional programming languages perform type checking of programs at runtime. Their language definition does not provide the opportunity of rejecting ill typed programs by static type checking at compile time. To make the benefits of static type checking available for dynamically typed languages, the approach of soft-typing was proposed. A softtyping system raises warnings an...

Optimal Representations of Polymorphic

Many type inference and program analysis systems include notions of subtyping and parametric polymorphism. When used together, these two features induce equivalences that allow types to be simpliied by eliminating quantiied variables. Eliminating variables both improves the readability of types and the performance of algorithms whose complexity depends on the number of type variables. We presen...
