Thanks. Writing games is the most exciting way to activate student brains.

Aren't you going to write real scheme compiler ? At least with call/cc.
Some time ago I've tried to implement r5rs->javascript compiler, but
lack of theory knowledges forced me to pause project and start studying 
some theory.
  AFAIK "call/cc" is incredibly useful for asynchronous communication 
with web server via XMLHTTPRequest, so i decided not to ignore it in my 

Will appreciate if you can give me any hints here.
