I don't know why it didn't occur to me before but Bard may actually provide a solution here.

Consider a little example code from the Bard repo:

(define method (fib n)
  with: ((n (exactly 0)))
  1)

(define method (fib n)
  with: ((n (exactly 1)))
  1)

(define method (fib n)
  with: ((n <fixnum>))
  (+ (fib (- n 1))
     (fib (- n 2))))

Notice that, like infix Dylan, Bard's method-definition syntax uses space-separated tokens ("define method"). There's nothing particularly hard about extended that to support adjectives, so that you could write:

(define sealed method (foo bar)
  ...)
