C++26: more constexpr in the core language (sandordargo.com)
Since constexpr was added to the language in C++11, its scope has been gradually expanded. In the beginning, we couldn’t even use if, else or loops, which were changed in C++14. C++17 added support for constexpr lambdas. C++20 added the ability to use allocation and use std::vector and std::string in constant expressions. In this article, let’s see how constexpr evolves with C++26. To be more punctual, let’s see what language features become more constexpr-friendly.
Fun with C++26 reflection: Keyword Arguments (pydong.org)
In this blog post, we’ll explore implementing order-independent keyword arguments for C++ through use of C++26’s proposed reflection features. I stumbled upon this technique while experimenting with reflection a few days ago and thought it might be worthwhile to share, as it nicely showcases just how powerful the proposed reflection features are.
C++26: Pack Indexing (sandordargo.com)
C++26 brings us pack indexing as a core language feature thanks to the proposal of Corentin Jabot and Pablo Halpern, P2662R3.
