[racket] the Dr{Scheme,Racket} repl isn't the one in Emacs

I'm at NEScala 2013 in Philly and the speaker, Ken Vogel, was talking about functional reactive programming in the context of using a Scala project called Notebook [1] to help run global hedge funds at Bridgewater [2].  In the middle of the presentation Matthias's blog post [3] of 2009-03-29 came up.  Lots of ooh and ahhs.  It struck me that no matter what language people are using, Racket continues to advise and influence the work of others.  It looks like several dozen people will be re-reading the post.
