If that was going to happen, then one thing it would need would be a
more generalized way of defining "order".  And even if that doesn't
happen, I'd really like a way of applying different orderings other than
the built-in ones.

So that, for example, one could have, say, a page which said

Title:Thing From The Black Lagoon
Author:Fred Nurk
Genre:SF
Summary:It came from the Black Lagoon

and other similar pages, and you could have a pagelist which said

(:pagelist group=Stories list=normal order={$:Genre}:)

and it would order it by the Genre field.  Or some other format like

        order=:Genre

And likewise, order=:Genre,:Author to give a multiple ordering.
