What I suggested was
(define-struct (ufo #:posn p #:vel [vel (velocity 0 0)]))
I also talked about
(define (ufo #:posn p #:vel [vel (velocity 0 0)]) #:struct)
but not seriously. Matthias took this further as a point against
changing.

IMO removing the parentheses around the fields makes more sense:
(define-struct ufo #:posn p #:vel [vel (velocity 0 0)])
or
(define-struct (ufo player) #:posn p #:vel [vel (velocity 0 0)])
because it's far more common (from a lisp perspective).
