[racket] DrRacket for the Truly Impatient V02, need help, beta testers

Along with the goodies enumerated by Nadeem, I use Typed Racket heavily so
for me the two biggest benefits I receive from online compilation are the
immediate feedback loop from syntactical errors and the type checking
errors as I'm developing on the fly.
