   Thanks a lot Daniel.   
      
   I looked at that location in the standard document. Though the wordings mention   
   both point of definition and point of instantiation, the examples only deal   
   with   
   point of definition cases. This makes it hard to understand the reasoning   
   behind such behaviour during point on instantiation :-(
