Hi Nobu, will the &: notation/feature be incorporated in 1.8.x series?
btw, i'd prefer max(&:length) over max_by..

Note the difference in using sort and sort_by, or max and max_by:

enum.max { |x,y| x.length <=> y.length }
enum.max_by { |x| x.length } # 1.9

I don't think so, but Symbol#to_proc was incorporated from
ActiveSupport.
