+multiple return variables -> supported

+variadic multiple return variables -> not supported as of now

+        (defun ff(a b ::: x y z ...) <--- can i support something like this???
+                (set x (+ a b))
+                (set y (+ x x))
+                (set z (+ 999 x))

+        (set-r v1 v2 v3 (ff 10 20))
+	(printf "%d %d %d\n" v1 v2 v3)
+
+	since va-get is used to get a variadic argument, can i create vr-put
+	to set a variadic return variable?
