Don't ask me; I learned Scheme five minutes before I wrote this.

In the case where 'y' and 'z' are elements to be added to the front of list 't', then I 
see in the manual that "apply" take the parts as if they were joined in a list. 
 But the old code made clear the structure
  (apply /operation/ /list/ )
which is lucky for me or I would have been lost.

But golly gee willikers, David, I'm truly out of my depth in Scheme here, so 
you should really take over this patch.
