摘要

代数效果和处理程序是一种方便的方法,用于构造具有基本有效操作的一元效果,并将语法与这些操作的解释分离开来。然而,传统处理程序的范围有些有限,因为并非所有副作用都是一元性质的。本文将代数效应和处理程序的概念从单群推广到广义单群,主要包括应用函子和箭头。为此,我们将范畴理论基础从自由代数转换为自由模群。此外,我们还展示了松散单函数如何支持跨不同计算类重用处理程序和程序,例如使用单函数处理程序处理应用程序计算。

Handlers for Non-Monadic Computations
Algebraic effects and handlers are a convenient method for structuring monadic effects with primitive effectful operations and separating the syntax from the interpretation of these operations. However, the scope of conventional handlers are somewhat limited as not all side effects are monadic in nature. This paper generalizes the notion of algebraic effects and handlers from monads to generalized monoids, which notably covers applicative functors and arrows. For this purpose we switch the category theoretical basis from free algebras to free monoids. In addition, we show how lax monoidal functors enable the reuse of handlers and programs across different computation classes, for example handling applicative computations with monadic handlers.
