   OK, I was able to compile and run your ccu.c, and at least on this   
   example it works as you've described it.  It looks interesting,   
   but I personally don't find it particularly useful, given that I   
   already have cdecl, I prefer its syntax, and it's easier to use   
   (and I almost literally could not care less about the number of   
   lines of code needed to implement cdecl).
