Inference in C++: The big picture

In every new standard, inference and type deduction has become more prominent in C++, making for perhaps the most remarkable evolution seen in any established programming language. From Function Template Argument Deduction in C++98, to `auto` in C++11, to generic lambdas in C++14, to Class Template Argument Deduction in C++17, to the high-profile introduction of Concepts in C++20, it is something every programmer now needs to understand, not just as individual features but as a coherent whole. Unfortunately, since inference has arrived piecemeal into C++, the big picture of how to program with it is often lost. Worse yet, idioms that used to be usable, like "almost always auto," are simply wrong in C++20.

In this talk, I will show how these seemingly individual features can combine in amazing ways in C++ 20 for best practices that can make your code more powerful, more performant, more maintainable and more understandable. I will illustrate these with nuts and bolts examples like how common code that used to take dozens of machine instructions can now use inference to run in a single instruction. By the end of the talk, I hope you will come out with not just a new understanding of this wondrous evolution but the skills and confidence to safely make the most of it
