Personally, I'd rather migrate to using abstract sequences (as in
Common Lisp), and have ranges be a kind of sequence.  Thus instead of

   (range-for-each f start end)

one would write:

   (for-each f (range start end))

IMO Scheme needs interfaces ...  Without them, we get this huge list
of SRFIs for different sequence-like types, and thus potentially a
R7RS-large with a huge number of procedures.  That way lies madness.
