map-constructor

[Richard Light <richard@xxxxxxxxxxxxxxxxx>]

I haven't seen any 'home-grown' versions of map-constructor in my
ramblings through the DSSSList archive, so I cooked up the following:

(define (map-constructor proc n1)
  (node-list-reduce n1
    (lambda (result sn1)
      (sosofo-append result (apply proc (list sn1)))
    )
    (empty-sosofo)
  )
)

This reflects what I understand to be the function of map-constructor,
and it certainly does what I was hoping it would do in my particular
application.

Could someone who knows a bit more than me about DSSSL check this out,
and advise whether it is ok?

Is there a version sitting somewhere that I haven't found?

Thanks,

Richard.
