As Simen mentioned, templates cannot be virtual. But you don't 
need to use a template, you can use a regular variadic method 
[1]. It's a bit more clunky to work with than template variadic 
functions. Or if all the arguments will be of the same type, you 
can use type safe variadic functions [2], which are easier to 
work with.
