    "Strained" indeed. I've only seen one - something about the integer
part of some power of a certain real number x. The strained part
being that you don't know what x actually is, you need to know
infinitely many primes to "construct" x in the first place.

    You want to be careful mentioning that name. Seriously - you
think having me around is a pain, it could be much worse...
