Hello World

Abstract

In this article, we present a formalization of the well-known "Hello, World!" code, including a formal framework for reasoning about IO. Our model is inspired by the handling of IO in Haskell. We start by formalizing the 🌍 and embrace the IO monad afterwards. Then we present a sample main :: IO (), followed by its proof of correctness.
