That is a concern, indeed, but there are many ways to attack the
problem:
- Arrange for the predicates to be "translucid", so you can test them by
groups that share the same predicate in a way that's a lot more
efficient (this will strongly depend on details). I hope we don't
have to go there.
- Delay the predicate filtering to the last stage and filter lazily, so
you can stop as soon as you have found enough completions to fill the
part displayed on screen.
- ...
In any case, this is all very hypothetical for now.
What we need is experience (and there is already some of that
experience, collected from the `smex` experiment).
