A practical monadic aspect weaver

Published in International Workshop on Foundations of Aspect-Oriented Languages, 2012

Abstract

We present Monascheme, an extensible aspect-oriented programming language based on monadic aspect weaving. Extensions to the aspect language are defined as monads, enabling easy, simple and modular prototyping. The language is implemented as an embedded language in Racket. We illustrate the approach with an execution level monad and a level-aware exception transformer. Semantic variations can be obtained through monad combinations. This work is also a first step towards a framework for controlling aspects with monads in the pointcut and advice model of AOP.
