I think this looks rather nice actually. Doesn't seem like too much
trouble to implement a such y-function and call it lambda or whatever
catches one's fancy.
+ for not needing to modify lua to implement it. A downside i can see
is that it wouldn't get compiled until y/lambda gets called, but i
could live with that.
