The parent's humorous wish is granted by the wizards of MIT Scheme (and, I daresay, even more fulfilled by Racket):

"Scheme is a statically scoped and properly tail-recursive dialect of the Lisp programming language invented by Guy Lewis Steele Jr. and Gerald Jay Sussman. It was designed to have an exceptionally clear and simple semantics and few different ways to form expressions. A wide variety of programming paradigms, including imperative, functional, and message passing styles, find convenient expression in Scheme."

I got it from R4RS. I imagine MIT Scheme also got it from there.

Maybe. Looks like R4RS got it from R3RS. :-)
