  And it's noteably slow due to it; c.p.s. made sense at that time, but modern hardware takes advantage of the existence of a stack much more aggressively. Chicken Scheme also uses it with a novel approach that allows the C stack to become the garbage collector which is still relatively fast as far as I heard.
