Well, it's not per spec: what you did accepts queries that are invalid

Quite honestly, I think that something that only handles functions as
LATERAL righthands is broken by design. It doesn't meet the spec, and
it's unlikely to represent much of a step towards a full implementation.
Remember Polya's Inventor's Paradox: the more general problem may be
easier to solve.
