Very nice!

One problem though. I think this has broken some uses of
`define/contract` in third-party code I have installed. Here's a
boiled-down snippet that shows the issue:

  #lang racket

  ;; breaks
  (define/contract (f x #:y [y 3])
    (->* (integer?) (#:y integer?) integer?)

  ;; contract-out ok with same contract
  (define (f x #:y [y 3]) x)

      [f (->* (integer?) (#:y integer?) integer?)]))

The error I see is:
  dc-bug.rkt:5:19: #%datum: keyword used as an expression
    in: #:y
