Racket is a very nice scheme setup. As a SICPer I initially wondered if I should use a scheme variant for my oldest son but I thought back to my youth and decided against it. in HS I wrote a TP program that plotted functions for my math class. It would run through the line entered looking for whitespace operators like * and + and only keywords like sin before (. Then it would write a .BAS file and run it in qbasic to plot ;) Having later taken SICP in first year CS was mind opening regarding REPL, but I really appreciated having that earlier experience and honestly I needed a certain maturity for the mental abstractness. There's a time for scheme, about the time someone is ready for learning calculus.
