Updated papers

• P2000R4. DIRECTION FOR ISO C++. Additions are highlighted in red, my eyes!! Accent on type safety, static analysis.
• P0592R5. To boldly suggest an overall plan for C++26, by Ville Voutilainen
• P2263R1. A call for a WG21 managed chat service. IRC -> Slack (Cpplang) -> Mattermost. CoC enforcement is a problem.
• P1068R6. Vector API for random number generation. Doesn’t address the problem of correct initialisation of random number generators.
• P1385R7. A proposal to add linear algebra support to the C++ standard library. This is a big one, voting record shows various details are being fleshed out.
• P1673R10. A free function linear algebra interface based on the BLAS. Huh, another one? Interop with the other proposal. Distinctive characteristics.
• P1967R9. #embed - a scannable, tooling-friendly binary resource inclusion mechanism. The C edition was accepted into C23. Come on, C++.
• P2392R2. Pattern matching using is and as, by Herb Sutter. Nothing on what’s changed in this version. Perhaps Cpp2 had some influence?
• P2561R1. An error propagation operator, by Barry Revzin (was: operator??). Looks a bit weird.

New papers

• P2687R0. Design Alternatives for Type-and-Resource Safe C++, by Bjarne Stroustrup and Gabriel Dos Reis
• P2657R0. C++ is the next C++. C++ can be improved with static analysis, which can be specified and configured per module. This creates dialects of sorts, but doesn’t add or remove anything from C++.
