   No, what is needed is to abandon the mistaken notion that a function
   returns a single result.  From day one, lists should have been allowed
   to the left of the replacement sign--this is not just for functions,
   but even for direct operators.  For example, the infamous frexp function
   in C should not have the syntax

	   y = frexp(x,&n);

   but

	   y,n = frexp(x);


Isetl has something of this sort.  In Isetl [1,2,3] is a tuple and
if you say
[a,b] := [b,a];
you have a swap routine.

[a,b,c] := f();

and f() returns [1,2,3] you will get the assignments that you want.
