Functional effect and streaming systems in Clojure

on YouTube ↗25m

" summary

Demonstrates a concrete effect model that replaces actions with descriptions and enforces structural concurrency so combinators carry supervision; shows a concrete Clojure/ClojureScript library Missionary library with implementations of pure operators (pure, bind, par) and the pitfalls of a naive par versus a canceling supervisor-aware version. Introduces a parking operator (async/await-style) that awaits both single-result tasks and flows producing multiple values, gives backpressure, cancellation on interruption, and supports discrete and continuous-time streaming; part of the hyperfiddle stack.
