Type-Like Frameworks for Controlling State and Aliasing

Abstract

Dijkstra's famous maxim "go to statement considered harmful" noted that spaghetti-like code was hard to reason about. However, in the presence of side effects and (especially) concurrency, spaghetti-like data is far harder to understand - not only in terms of the full behaviour of a program but also in terms of lesser properties such as performance prediction on multicore architectures. We present various compile-time techniques for controlling stateful operations and investigate some of their connections. These techniques include sub-structural type systems, effect systems, typestate, session types, contracts, linear and quasi-linear types, monads, separation logic and ownership types.
