我有两个功能;

  foo ( A, B, C ) 

  bar ( D, E, F ) 

我想 ;

 | --------- |
foo         foo 
started    finished

             | -------  |
            bar        bar 
          started    finished

                        | ------ |
                        ^^^^^^^^^^
                         concatenate two list namely C and F 

如何同步这两个功能以便按顺序工作?

你能举个例子吗?
