title: access an instance method of a class from another module's instance method
body: <p>I have a class which declares a number of instance methods</p>
  
  <pre><code>class User &lt; Group
    def get_name
  
    end
  
    def show_profile
  
    end
  
    def get_task(task_id)
      #some logic
    end
  
  end
  </code></pre>
  
  <p>And I want to call some of these methods from within a module. I can do it with Include statement. </p>
  
  <p>include Users brings in all of the methods from User class. In this case I only want get_task and explicitly do not want get_name, show_profile etc..</p>
  
  <p>I have a Tasks module which also has set of methods and one of those methods calls get_task method of User class.</p>
  
  <pre><code>    module Tasks
        class Project
          def design
            tid = 12
            design_task = get_task(tid)
          end
        end
     end
  </code></pre>
  
  <p>How this can be achieved without including other unnecessary methods of that class. Please help.</p>
