Hi guys, I noticed strange situation with module refinements.

There is difference with using methods which you refine. 

*User.new.users* will return ["a", "b", "c", "d%"]
*User.new.users_not_work* will fail with error  **"undefined method `apply_user_name!' for "a":String"**


     module Punctuations
        refine String do
          COMMON_PUNCTUATION = %w(. , ! ?)

          def apply_user_name!
            chop! if COMMON_PUNCTUATION.include?(last)
          end
        end
      end

      class User
        using Punctuations

        def names
          ["a", "b.", "c!", "d%"]
        end

        def users
          names.each { |word| word.apply_user_name! }
        end

        def users_not_work
          names.each(&:apply_user_name!)
        end
     end
