Indeed, this is a disadvantage of the "function call" syntax.
Human input of the arguments of more complex queries
best supported by a GUI, much like existing SQL query
front ends.
Would it be possible to privide such a GUI automatically
(by introspection) given a set of Query classes of which objects
can be mixed to form a query?
