That will work... My problem is conceptual - Query interface is too
generic to imply a single result type parameter. There are updating
queries, but even selecting ones like SQLTemplate and ProcedureQuery
can return multiple results of different type (which is abstracted in
org.apache.cayenne.QueryResponse).
