All jokes aside, reductionism is quite intuitive and solves some  
fundamental "user interface" issues.  Gambit uses it when displaying  
environments and continuation frames (see example below).  It just  
doesn't use it to print results at the REPL, mainly because  
historically most Scheme textbooks do not use it.
