I unanimously agree here. It's hard to come up with good use cases
and strategies, so we should build it bit by bit and watch it grow.

Coincidentally, this also fits in with my initial ramblings
(cited by Daniel) about LIMIT and the likes. My first idea here
was to add this functionality as keyword parameters to
GET-INSTANCES-*.
