I am fond of match-define too. The name is a little long, so I use this to
get shorter names:
(define-syntax defm (make-rename-transformer #'match-define))
(for/list ([a+b some-sequence])
(defm (list a b) a+b)
a)
Another construct with too long a name is define-values:
(define-syntax defv (make-rename-transformer #'define-values))
