[racket] translate from Racket to Common Lisp

It is flattering for the Racket language that someone would go to all 
the trouble of making a translator so that they could continue to 
program in Racket, even though they were using a Common Lisp backend. :)

I think that blog entry was an introductory programming tutorial, and it 
was not focused on performance.

Before you spend time on a translator that might be a distraction from 
your real work, perhaps you will find that Racket programs can be 
written to be fast enough for your needs, using the normal Racket 
compiler and virtual machine.

What kind of programs are you making, and what are your requirements?
