[racket] mysterious error message

   I'm running DrRacket version 5.2.

   In Pretty Big, I get the following error message.

   The variable cl is highlighted in the definitions window, and in the 
interactions window the following text is displayed (partially in red).

   cl: expected cl in: cl

   In R5RS the code runs fine.

   What does this error message mean?  My guess is that it thinks that the 
function is receiving the wrong parameters, but that's incorrect.
