Troll Driven Development: Implementing Functional Effects by Way of Self-Lobotomy

on YouTube ↗30m

" summary

Live-codes a ZIO/Cats-IO style effects runtime in ~15–30 minutes, building AST nodes for succeed, map, flatMap, suspend/effect, async, fork and a simple fiber with join, using Scala and the global execution context. Tests show pure succeed/zip/map work, suspend and async run, and fiber + join concurrency executes though tiny workloads sometimes appear sequential. The result is a semi-functioning functional effects library that demonstrates interpretation, forking, and basic parallel composition.
