question: does the Indexer prop->classes ever match an Union component? I am calling transact! on the reconciler, idk if an Union can add exclusive props.

For those looking to run Om Next queries against SQL databases, I’ve just released fulcro-sql. It can follow most kinds of standard SQL joins (to-one, to-many, many-to-many with a join table) in forward or reverse. Tested against PostgreSQL and MySQL. https://github.com/fulcrologic/fulcro-sql.
