   It can't work. The type information is already lost and only available   
   at runtime as part of the format string (assuming the programmer did   
   not make a type error). That's just too late to feed a variadic   
   function template -- unless you want the compiler to create a LOT of   
   function template instances in advance for every possible situation   
   you *could* run into at *runtime* up to a certain maximum number of   
   parameters. But that would be incredibly wasteful ("template bloat   
   explosion").
