These should be

(define mapping/ordered mapping)
(define mapping-unfold/ordered mapping-unfold)

Hi, Marc.  I just noticed these lines in srfi/146.scm in the new draft of SRFI 146:

(define mapping-ordered mapping-ordered)
(define mapping-unfold mapping-unfold)

What is the purpose of these lines?

Thanks.
