Super slow and runs out of memory, but that's a feature 😃 It's just for prototyping, and you should be throwing the prototype away and rewriting it one level down where it's easier to be memory-efficient and fast. To that end, I think I'll focus now on making it super easy and nice to write tests while prototyping, so that rewriting becomes less risky down the road.
