Caterpillar

Anyway, Caterpillar's approach to compiler errors is still very experimental. And that's reflected in the developer experience. Right now, there isn't even a centralized list of compiler errors and other problems anywhere (tracked in #26).

Usability will improve over time, and we'll see how this approach works out. But I think it's promising. And in the context of Caterpillar, with its focus on (and design decisions made around) tooling, maybe essential.
