... if you don't mind compile-time variadic behavior.  I.e. can't pass 
func1 around as a function pointer, can't make it a polymorphic member 
in a class, you don't mind different code being generated for every 
place you call it, don't mind making the function's definition available 
as source code ... etc.

But if you are ok with that then, yeh, variadic templates work quite nicely.
