Introduction to C++ 23

Whoever might think that a significant C++ standard is followed by a small C++ standard is wrong. C++23 will provide just as powerful extensions as C++20 does. Ville Voutilainen’s proposal P0592R4 “To boldly suggest an overall plan for C++23” gives a first idea of the upcoming C++23 standard. Ville names seven features.

• C++23
  • Library support for coroutines
  • A modular standard library
  • Executors
  • Networking
• C++23 or later
  • Contracts
  • Reflection
  • Pattern Matching

The first four features are aimed for C++23, and the remaining three have no specific schedule. Probably, reflection, pattern matching, and contracts are successively added to the C++ standard.

“Prediction is very difficult, especially if it’s about the future.” (Niels Bohr). Consequently, you should read this chapter as my best attempt to predict the C++ future.
