Developer builds functional programming language over a simple sum

Original: Needed 1+1, built a functional programming language

A programmer has written about how a seemingly trivial task — evaluating 1+1 — spiralled into building an entire functional programming language. The account, published on a personal blog, describes the chain of design decisions that turned a small arithmetic exercise into a full interpreter. Readers on Hacker News have been discussing the story, a familiar genre of side projects where simple goals grow into ambitious systems.

Why now: The idea that a trivial arithmetic problem escalated into building a whole language is an entertaining and relatable software engineering story.
