FRP and Functional Game Programming
summary
Explains concrete results: a casual game built in Haskell + Elerea, running a 60 fps game loop with signal generators, dynamic per-bullet signals and level subnetworks that can be swapped or put to sleep, integration strategies for a black‑box physics engine via execute/effectful, and measurable tradeoffs — easy pure-function game logic and replayable input captures for property testing versus many streams, potential GC/performance concerns and the work needed to prune or optimize streams.
