Could <2> not be a shorthand for (<> 2) — for single-digit numbers?
That would give brevity and flexibility.

How would this look for three steps? Like this?

(receive (a b) (receive (x y) (floor/ 5 2)
                        (values (- y x) (+ y x)))
         (* a b))

Compared to

(chain (floor/ 5 2)
       (- <2> <1>)
       (* <1> <2>)

Best wishes,
