Class Template Argument Deduction in C++17

Explore Class Template Argument Deduction (CTAD) in C++17 through this comprehensive ACCU 2018 conference talk by Timur Doumler. Delve into the practical applications of CTAD and automatic deduction guides for writing cleaner, more concise code. Learn how to effectively use CTAD with the C++ standard library and when designing custom classes. Understand the language rules behind CTAD, including when and how to implement user-defined deduction guides. Discover potential pitfalls such as unexpected template argument deductions, constructor selection issues, and unsafe code scenarios, along with strategies to avoid them. Cover topics including template argument deduction in C++98, vector implementations, sequence containers, maps, locks, mutexes, smart pointers, type identity idioms, templated constructors, std::function, SFINAE, aggregates, and CTAD's interaction with nested types and smart pointer conversions.
