 The span method takes two tokens and matches the shortest or longest balanced match (if True). It assumes there are no escape characters (such as \ or ""). So we just repeatedly strip out the longest balanced comments until there aren't any left (span returns the empty list). If a comment was unbalanced, span  would fail but this code doesn't check that and just assumes no more matches.
