# Why? In a work related context, I had to create a hash algorithm working on a finite set of values ([0, 0xFFFFFFFF]) to output a non sequential serie from a sequential one (the output had to be rendered as a UUID. Basically, I wanted to avoid generating UUID looking like 00000000-0000-0000-0000-000000000001, that will definitely appear to be sequential and easily abused to find other IDs. # The transformation Previously I called it a hash, it’s more like a map function (or transform function for my C++ folks), operating on [0, 0xFFFFFFFF] -> [0, 0xFFFFFFFF] where the sequential aspect is lost.

The evolution of the C++ language continues to bring powerful features that enhance code safety, readability, and maintainability. Among these improvements, we got changes and additions to enum class functionalities across C++17, C++20, and C++23. In this blog post, we’ll explore these advancements, focusing on initialization improvements in C++17, the introduction of the using enum keyword in C++20, and the std::to_underlying utility in C++23.

They are two kinds of undefined-ness, one for runtime and one for compile-time.

WG21 has a strict schedule (see P1000) by which we ship the standard every three years. We don’t delay it. Around this time of each cycle, we regularly get questions about “but why so strict?”, esp…
