Chapter and Verse: An Outsider's Overview of Epic Games' New Language
summary
Verse is a logic‑functional language that aims to collapse types and values into one system, with a Verse Calculus underpinning goal‑driven, backtracking evaluation, a Curry‑style type approach, and a closed effect system (converges/decides/suspends, reads/writes/allocates). A beta subset runs in Fortnite creatives via Unreal Editor for Fortnite; design goals claim billion simultaneous users and pervasive transactions (atomic, O(1) writes under contention). A reference implementation in Haskell and an in‑language verifier are promised, full standalone release still pending.
