Nothing is wrong with recursion if it is useful or necessary and not burdensome.

I haven’t thought as deeply about implementation as Emile has (but expect to at some point), but it seems like it might be unnecessary and burdensome here. Maybe one way out here is to leave the definition as it stands but disallow more than one or two levels. Is there a use case 3, 4, 5, … levels of recursion? If so, is that the best way to handle the use case?
