=head1 NAME
What is a PQF parse-tree good for? Not much. You can render a
human-readable version by invoking the top node's C<render()> method,
-which is probably useful only for debugging. If you want to do
-anything useful, such as implementing an actual query server that
-understands PQF, you'll have to walk the tree.
