Or when starting position is given.

  last = 0
  while index = words.index(PATT, last)
    puts index
    puts $&
    last = Regexp.last_match.end(0)
  end

BTW, assignment to `last' at the end of the loop annoys me, it'd be nicer
if I can write as:

  last = 0
  while match = words.match(PATT, last)
    puts match.begin(0)
    puts match.to_s
    last = match.end(0)
  end
