We're not doing lambda here, only extending a facility that we rely on
today. The function would be named, for one. I don't know what you mean
by SQL being lispish here, and I can't imagine why it would be something
to avoid.

Currently we don't have CALL, and we have DO which is not a query but a
utility statement. Are you proposing to implement CALL? What would be
the difference between making DO a query and having CALL?
