Algebraic effects and handlers is an increasingly popular approach to programming with
effects. An attraction of the approach is its modularity: effectful programs are written against …

We present guarded interaction trees—a structure and a fully formalized framework for
representing higher-order computations with higher-order effects in Coq, inspired by domain …

Algebraic effects & handlers are a modular approach for modeling side-effects in functional
programming. Their syntax is defined in terms of a signature of effectful operations, encoded …

This paper presents a novel formalisation of algebraic effects with equations in Cubical
Agda. Unlike previous work in the literature that employed setoids to deal with equations, the …

Develo** programming languages is a difficult task that requires a lot of time, effort, and
expertise. Reusable programming language components make this task easier, by allowing …

Programming languages providing high-level abstractions can increase programmers'
productivity and program safety. Language-oriented programming is a paradigm in which …

Develo** and maintaining software commonly requires (1) adding new data type
constructors to existing applications, but also (2) adding new functions that work on existing …

Programming languages providing high-level abstractions can increase a programmers'
productivity and the safety of a program. Language-oriented programming is a paradigm in …

Algebraic effects & handlers have become a standard approach for side-effects in functional
programming. Their modular composition between different effects and clean separation of …

Despite the intended use for prototy** or as a first step towards giving semantics to a new
programming language, interpreters are often monolithic and difficult to extend. Higher-order …
