  20 ;;; (gbh) some of these are duplicated in r4rs. This is probably a bit
  21 ;;;       more thorough, though (maybe overkill? I need it, anyway).
  22 ;;;
  23 ;;;
  24 ;;;       Also: it will fail on the ass*-ref & remove functions.
  25 ;;;       Sloppy versions should be added with the current behaviour
  26 ;;;       (it's the only set of 'ref functions that won't cause an
  27 ;;;       error on an incorrect arg); they aren't actually used anywhere
  28 ;;;       so changing's not a big deal.
