Introducing Labrea: How Embracing Declarative Functional Programming Can Lead You Out of the Tar Pit
summary
Labrea is a Python framework that replaces fragile argument plumbing with declarative options as JSON and data sets that auto‑wire dependencies via a data set decorator, letting code pull configuration and queries when evaluated. A Kroger coupon recommender of ~20,000 lines and servicing 10 million households with 1,500 offers is rewritten into a rules‑driven, composable system; unwanted function coupling disappears, debugging becomes direct evaluation of a data set, and the rebuild succeeds at simplifying complexity.
