I    have   an   ExternalMethod  Article that  may only be called once. 
But I want to use the returnvalue, a string,   in two places. 
  

Use of namespace doesnot solve the problem 
 <!--#with  "_.namespace(story_id=Article)"--> 
<!--#var story_id--> 
<!--#var story_id--> 
<!--#/with--> 
The function is still called Twice  

Instead, use the namespace to assign the result of the function to
'story_id',

<!--#with "_.namespace(story_id=Article())"-->

 <!--#var story_id--> <!--#var story_id-->

<!--#/with-->

This way, you only call the function once (in the namespace call) and
assign its result to story_id.  Thus, when you #var story_id it's just
displaying a string and not calling a method.
