Because the problem is #lines, not #each_line. My understanding is
that ultimately Ruby 1.9 wont have String#each_line at all, and you'll
instead have to do String#lines#each to get this. More, String#lines
without #each returns an enumerator. So, instead of String#lines, use
String#by_lines. Where I personally disagree with David is that we
shouldn't have String#lines at all. I'd rather have
String#by_lines#to_a.
