Functional Programming in the Large - Status and Perspective
summary
Argues that large‑scale functional know‑how remains folklore and largely absent from mainstream software architecture, reports practical experience cross‑pollinating the two communities, and points to concrete levers: module systems, pure core with effectful edge, combinator libraries and design recipes plus property‑based testing and type‑based refactoring. Describes building a self‑contained e‑commerce platform for a major German retailer (5–6 teams, ~50 developers, ~100 people overall) and pushes for documenting patterns and a JFP category for functional software architecture.
