Template metaprogramming is a vast subject, but there are a small number of basic fundamental idioms that are used over and over. Mastery of these idioms will help in reading, writing, and using modern C++ code. The type traits that come as part of the standard library are incredibly useful, but at times can be thought of as some form of dark magic.

In this tutorial, we will explore some of the fundamental idioms of template metaprogramming by implementing a good portion of the type traits from the standard library. In so doing, attendees will come away with a solid understanding of how to apply the fundamental template metaprogramming idioms to solve problems including, but not limited to, standard type traits.
