Safe C++ proposal is not being continued

Summary

The Safe C++ proposal has been discontinued in favor of 'Profiles,' a less radical approach to improving C++ safety. 'Profiles' aim to constrain existing features rather than introduce new ones, making them more adoptable. The author believes 'Profiles' are a more realistic path forward for C++.

Key Takeaways

1. The Safe C++ proposal, aiming for Rust-like safety in C++, is no longer being pursued.
2. The C++ committee has prioritized 'Profiles,' a less radical approach, over Safe C++ for improving safety.
3. 'Profiles' define modes of C++ that impose constraints on language usage to guarantee safety properties, primarily through compile-time checks.

Credibility & Bias Reasoning

Credibility assessment: The article is a personal blog post, but the author references specific proposals and committee decisions within the C++ standardization process. The author also links to official documents related to the 'Profiles' proposal. While subjective opinions are present, the core information regarding the Safe C++ proposal's discontinuation and the prioritization of Profiles is verifiable.

Bias assessment: Pragmatic C++ Evolution. The author expresses a preference for the 'Profiles' approach over 'Safe C++', framing it as a more realistic and adoptable solution for improving C++ safety. This perspective favors a gradual, less disruptive evolution of C++ rather than a radical shift towards a Rust-like model. The author acknowledges the limitations of Profiles but views them as a practical compromise.
