Returns

Example



   class Product(string name, string version)
   {
     string _sprintf()
     {
       return sprintf("Product(%s/%s)", name, version);
     }
   }
   map(({ ({ "pike",   "7.1.11" }),
          ({ "whitefish", "0.1" }) }),
       Function.splice_call, Product);
   ({ /* 2 elements */
	 Product(pike/7.1.11),
	 Product(whitefish/0.1)
   })
