                                     SelectQuery

A complete query excluding CTEs.

The main ugly thing here is the set limit; the querySpecification has max of the limits of the children, if existing, otherwise to None.

Other than that, we hand through attribute access to our first child.

If there is a set expression on the top level, this will have a complex structure; the first-child thing still ought to work since after annotation we'll have errored out if set operator arguments aren't reasonably congurent.
