Comment (by simonmar):

 I don't think that would be deterministic enough to be a reliable API. You
 could imagine the compiler making different optimisation choices which
 would change whether a function refers to CAFs or not - e.g. full laziness
 can do that, and then your program either works or not depending on
 whether optimisation is turned on.
