[racket-dev] shared no longer works on cons?!?

Ryan, I noticed this seems to be a problem in full Racket as well: try

#lang racket

(define web-colors
 (shared ([W (cons "white" G)]
          [G (cons "grey" W)])
   W))

(rest web-colors)

Robby privately wrote to say it should be regarded as a bug.
