[racket-dev] 5.2.0.1: displayln appears to write to console from where drracket was launched

The first step would be a compile-time IO console. 

The second step would be a compile-time interaction mode. 
This would fit right in with Ryan's past work. It would mean
compile the Def Window (as in CS) and make for-syntax values
available at the repl for experimentation. Then again, I might 
have had too much coffee :-)
