What is "template normal programming"? It's template metaprogramming without so much of the "meta" part! During this talk, I promise not to mention SFINAE, or recursion, or standard type traits. We'll focus on the common scenarios "I think this code could benefit from templates, but I don't understand how to organize it;" "I can't get anything to compile without errors;" and "My coworker wrote some template code and I don't understand any of it."

In Part I of the talk, we'll start with function templates and class templates, then explain variable templates (new in C++14) and template aliases (new in C++11). We'll do a deep dive into template type deduction; then talk about full and partial specialization; and finish up with an example that motivates the final feature of C++11 template syntax, explicit instantiation.

In Part II of the talk, we'll begin by demystifying tag dispatch and traits classes; discuss situations in which you have to add disambiguating "template" or "typename" keywords (and why); and do a deep dive into the rules of what gets instantiated when and where. We'll revisit template type deduction just long enough to explain how it works for variadic templates; and explain two common template idioms — the Curiously Recurring Template Pattern and the Mixin Pattern.
Time permitting, we'll finish by exploring the big new features of templates according to the C++17 Draft Standard:
- template
- type deduction for class template constructors
- explicit deduction guides
