Comment (by RyanGlScott):

 I will admit that the devil on my shoulder is trying to coax me into
 implementing this idea. But at the same time, the angel on my other
 shoulder is saying I should wait until we have `QuantifiedContexts`, which
 would give us a principled solution to this problem.

 I'm unable to pick a side at the moment, so I'll simply wait until I've
 heard more feedback.
