That makes sense. When people are sleeping, they're non-functional,
ergo a programming language that can sleep is non-functional :)

Seriously though... this ties in with the other issues about *purely*
functional languages being rather impractical, and the purity
generally being sullied some by things like monads (which I still
don't understand, despite the explanations in another thread). So what
happens if you have a monad "print to the console" in place of Steve's
time.sleep example? Will you get one execution of it or two?
