Type punning done right - Javier Lopez Gomez

Since C++11, the ISO C++ committee agreed on shipping a new version of the standard every three years. Even if C++14 and C++17 were considered "minor" releases, a number of new features are introduced into the C++ language core or its standard library with each new release. Yet, some of those features are not always well-understood by the average C++ developer. In this regard, one of the recurring topics is how to properly do type punning in C++, when (and why) certain forms of reinterpret_cast​ result in undefined behavior, and how the introduction of std::launder​ (C++17), std::start_lifetime_as​ (C++23), and std::bit_cast​ (C++20) fit in the picture. To make matters worse, the normative text for ISO C++ does not target average developers, and the well-known cppreference.com site is not much clearer about it. Improper use, however, results in non-portable code and may lead to hard-to-debug issues when compiler optimizations hit in.
