Recently on StickyBits, a nice primer on variadics:

Variadic Templates

by feabhas

From the article:

In this article we’re going to look at a new feature of templates in C++11 -- the concept of the variadic template.

Variadic templates allow us to create functions and classes, not only with generic types, but also a variable number of generic types.

If you haven’t been following along with the template articles, I’d suggest you read this article first before continuing.
