multiple variable reference

[haahr@mv.us.adobe.com (Paul Haahr)]

as i've noted to the list, the next version of es will have multiple
variable assignment.  that is,

	x y z = 1 2 3 4

is the same as

	x = 1
	y = 2
	z = 3 4

by symmetry, i think that

	$(x y z)

should be equivalent to

	$x $y $z

before people reject this idea out of hand, i want to point out why
i think that this makes sense.  if you have

	foo = a b
	$foo = 1 2 3

then it makes sense that

	$foo

would expand to

	1 2 3

opinions?
