[racket-dev] wishes

During my experiments last week, I came up with two more wishes for Racket:

1. Python seems to provide the following unit testing functionality:

   if a file/module is run as 'main', the test suites are run;
   if it is required into some other file, the tests aren't run. 

   It looks truly convenient. I believe we should be able to write a 
   define-test-suite macro that can do that too. 

2. We need some simple refactorings in DrRacket, e.g., 

   (define (f y)                 (define (f y)     
     (define x y)	==>        
     ... x ... x ...)	           ... y ... y ...)

   Could this be started as an REU project at NWU? 
   Or is this still a potential research=y MS-level project?
