Oh, only five other languages? Come back after your twentieth and we'll talk... Now seriously - in which Scheme did you "write"? Racket has excellent debugger

Oh, only five other languages? Come back after your twentieth and we'll talk... Now seriously - in which Scheme did you "write"? Racket has excellent debugger and brilliant contract system and exceptions, not to mention a repl and powerful type system. I'm sure you didn't want to display your lack of experience and knowledge, it just happened; I won't hold it against you, just don't write anything more about the thing you know nothing about.
