I think it's more useful because having Query objects you can suck off
disk / db / memory quickly means you can save exactly what you built,
even if there's no terribly good /single/ input format. So you might
have an input format, and then do something to it, and allow the user
to mix some other stuff - having a serialisable representation here is
easier than having to write your own.
