Hey, Carlin! Nice to see you here in comments! (Waving "hi" to the Malloy team.)

Usually, the experience would look like this: one directly develops the data model in YAML (with only bits of SQL, if needed) and instantly explores metrics. No need to start with SQL in a separate tool/place (1), no need to use the API to check metrics (2) (for that, we have Playground, an interactive UI tool), and, thus, no need to compare results to raw SQL (4). You iterate but changing the data model and seeing the metrics in an instant, quite similar to how you work with Malloy, if I may.
