hi -- no dont do this. any 'nil' you find in cm's scheme source code is 
a bug. it should either be #f or (), depending on whether 'nil' is 
standing for boolean false or the empty list in the current context. if 
you find a nil, please let me know which file. or maybe i should grep 
the sources right now

btw  if portability is an issue for your class, cm defines 'true' and 
'false' variables so that you dont have to hardwire boolan values like 
#f or nil in your code
