Sorry, that came out all wrong. What I meant was that it's neat 
to be able to do anonymous recursion without having to resort to 
tricks like the Y-Combinator. However, after some fiddling, it 
seems that this is actually not usable with anonymous functions, 
or at least, I couldn't find a way to do it.
