Yes, Bento connects very easily to the outside world, and once you do
side effects are unavoidable. This would be true of any functional
language capable of calling external methods, no? I'm assuming that
such real-world exceptions are accepted by real-world functional
programmers -- it would be hard to do many useful things otherwise.

If I can state with accuracy "Bento is a functional language like
Scheme is" I'll be satisfied :)
