[plt-scheme] DrScheme frustration

There is a rationale for this REPL behavior at the novice level, and  
others have provided you with the short-cuts to re-trace your  
interactions.

;; ----

But if there's someone out there with extra time on his hands, how  
about a tool for capturing the content of the REPL as a test suite  
(say using SchemeUnit)? That way you can explore things interactively  
and you can also have your cake and turn this whole lot of work into  
something useful.

And btw, this could also be a JaneSt project
