Common Lisp already has a notion of function names as lists, in the  
form of '(setf function-name). So that case would have to be covered  
as well.

I would not like to go that route because I recall reading other  
discussions about extending acceptable function names, with some  
ideas about other indicators beyond 'setf. I prefer not to create  
opportunities for potential clashes here.

Of course, your suggestion would have the advantage that it saves  
some space. I have already been hit by this a couple of times, trying  
to fit examples of layered methods in papers. ;) In your experience,  
how much better is your proposed syntax?


Cheers,
Pascal
