 FWIW, this is also the error encountered by the stepper tests in all  
 of the test cases that involve running the stepper on non-teaching  
 languages.  The stepper doesn't _need_ to run on non-teaching  
 languages, so this is a lower priority, but I would love to fix it.

 I think that the debugger is pretty important...  The bugs that I
 reported are from someone on the irc channel who asked about it.

 The problem happens when a tool adds code to the a program, and when
 the added code uses `#%app' from `scheme/base'.
 
 The solution is to explicitly use `#%plain-app' for the added code.
 
 I'll fix the debugger...
