I was scolded highly about that by Uri, back when my article[1] about
closures. I, too, felt that foo() should be called a closure, but Uri
seemed so convincing. If you're going to let me say that functions that
refer to lexical variables in such a fashion are closures, thank you, I
can return my normal "sane" self.
