Of course, something might break if we added a new statement type which

set against adding some Assert(IsA()) calls here, but I don't see the point.

gram.y has a long comment before select_no_parens regarding why we

It talks about not doing '(' SelectStmt ')' "in the expression grammar". I don't see what that has to do with this patch.
