Doc Date 2026-10-18 Mailing Date 2026-10 Pre-Búzios Author(s) Barry Revzin, Michael Park, Zach Laine, Bruno Cardoso Lopes Target Audience EWG Tracking issue View on GitHub Abstract One pattern that will occur with some regularity with pattern matching [[P2688R6] (Pattern Matching with `match` and `case`)](https://wg21.link/p2688r6) (and [[P2806R5] (do expressions)](https://wg21.link/p2806r5)) is the desire to produce values for some patterns but not for all. Consider the following simplified example:

Doc Date 2026-10-23 Mailing Date 2026-10 Pre-Búzios Author(s) Barry Revzin, Daveed Vandevoorde, Andrei Alexandrescu Target Audience EWG Revisions R0 Tracking issue View on GitHub Abstract This is a follow-up to [[P3294R2] (Code Injection with Token Sequences)](https://wg21.link/p3294r2). In that paper, we argued that the right model for code generation in C++ is through token sequences by comparing to other potential models. In short, we believe that code generation in C++ must be C++-shaped, must be able to generate all of C++, and must allow for the full use of C++ in that genera
	P4424R0	[[indeterminate]] for non-static data members	Barry Revzin B. Revzin	EWG	2026-10-23	2026-10
Doc Date 2026-10-23 Mailing Date 2026-10 Pre-Búzios Author(s) Barry Revzin Target Audience EWG Abstract [[P2795R5] (Erroneous behaviour for uninitialized reads)](https://wg21.link/p2795r5) was adopted for C++26 and implemented in gcc 16. In practice, it ensures that automatic storage duration variables are initialized unless they are marked `[[indeterminate]]` — both [gcc](https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#index-ftrivial-auto-var-init) and [clang](https://clang.llvm.org/docs/C
