…mpiler-errors more eagerly discard constraints on overflow We always discard the results of overflowing goals inside of the trait solver. We previously did so when instantiating the response in `evaluate_goal`. Canonicalizing results only to later discard them is also inefficient 🤷 It's simpler and nicer to debug to eagerly discard constraints inside of the query itself. r? `@compiler-errors`
