  snip : (is-a?/c snip%)
Applies f to all snips in the parent of snip, starting with snip.

procedure

(for-each-snip f first-snip more ...)  void?

  f : ((is-a?/c snip%) . -> . any/c)
  first-snip : (is-a?/c snip%)
  more : list?
Applies the function to each snip in the parent of first-snip, starting with first-snip. If more lists are supplied, they are used for extra arguments to f, just like extra lists provided to for-each.
