This presentation is a tutorial covering multiple metaprogramming topics. It builds upon last year's "Template Metaprogramming: Type Traits." That talk walked you through template metaprogramming fundamentals by implementing some basic type traits. This tutorial demonstrates how to build upon these basic building blocks to solve real world problems.
For example, we will explore how to manage types as plain lists and associative collections. However, we will not just demonstrate how to sort a collection of types, but also some practical use cases where such techniques provide significant advantages, both in representation and runtime performance.
We will look some explicit real world examples where we trade an upfront compile time cost for faster runtime performance. We will also explore ways to measure the compile time costs so that we can make educated decisions about how to improve the compile time performance, and determine if that cost is worth the runtime gain.
Thus, the tutorial will walk through a number of metaprogramming techniques and tricks, but with the goal of applying them to solve several explicit real world problems, all the while being very aware of the compile time costs.
