Doc Date 2025-06-20 Mailing Date 2025-07 Post-Sofia Author(s) Dan Katz, Barry Revzin, Andrew Sutton, Sam Goodrick, Daveed Vandevoorde Target Audience WG21 Tracking issue View on GitHub Disposition Date 2025-06Adopted Abstract This paper proposes a new kind of statement that enables the compile-time repetition of a statement for each element of a tuple, array, class, range, or brace-delimited list of expressions. Existing methods for iterating over a heterogeneous container inevitably leverage recursively instantiated templates to allow some part of the repeated statement to vary (e.g., by type or constant) in each inst

Doc Date 2025-06-20 Mailing Date 2025-07 Post-Sofia Author(s) Barry Revzin, Wyatt Childers, Peter Dimov, Andrew Sutton, Faisal Vali, Daveed Vandevoorde, Dan Katz Target Audience CWG LWG Tracking issue View on GitHub Disposition Date 2025-06Adopted Abstract This is a proposal for a reduced initial set of features to support static reflection in C++. Specifically, we are mostly proposing a subset of features suggested in [[P1240R2]](https://wg21.link/p1240r2):
	P3293R3	Splicing a base class subobject	Barry Revzin B. Revzin , Peter Dimov P. Dimov , Dan Katz D. Katz , Daveed Vandevoorde D. Vandevoorde	CWG LWG	2025-06-20	2025-07
Doc Date 2025-06-20 Mailing Date 2025-07 Post-Sofia Author(s) Barry Revzin, Peter Dimov, Dan Katz, Daveed Vandevoorde Target Audience CWG LWG Tracking issue View on GitHub Disposition Date 2025-06Adopted Abstract There are many contexts in which it is useful to perform the same operation on each subobject of an object in sequence. These include serialization or [formatting](https://www.boost.org/doc/libs/1_85_0/libs/describe/doc/html/describe.html#example_print_function) or [hashing](https://www.boost.org/doc/libs/1_85_0/libs/describe/doc/html/describe.html#example_hash_value).

Doc Date 2025-06-20 Mailing Date 2025-07 Post-Sofia Author(s) Daveed Vandevoorde, Wyatt Childers, Dan Katz, Barry Revzin Target Audience WG21 Tracking issue View on GitHub Disposition Date 2025-06Adopted Abstract Ever since writing [[P1240R0] (Scalable Reflection in C++)](https://wg21.link/p1240r0), but more so since [[P2996R0] (Reflection for C++26)](https://wg21.link/p2996r0), we have been requested to add a capability to annotate declarations in a way that reflection can observe. For example, Jeremy Ong presented compelling arguments in a post to the [SG7 reflector](https://lists.isocpp.org/sg7/2023/10/
	P3491R3	define_static_{string,object,array}	Barry Revzin B. Revzin , Wyatt Childers W. Childers , Peter Dimov P. Dimov , Daveed Vandevoorde D. Vandevoorde	CWG LWG	2025-06-20	2025-07

	P3560R2	Error Handling in Reflection	Barry Revzin B. Revzin , Peter Dimov P. Dimov	LWG	2025-06-20	2025-07
Doc Date 2025-06-20 Mailing Date 2025-07 Post-Sofia Author(s) Barry Revzin, Peter Dimov Target Audience LWG Tracking issue View on GitHub Disposition Date 2025-06Adopted Abstract In [[P2996R12] (Reflection for C++26)](https://wg21.link/p2996r12), we had to answer the question of what the error handling mechanism should be. We considered four options:
	P3726R0	Adjustments to Union Lifetime Rules	Barry Revzin B. Revzin , Tomasz Kamiński T. Kamiński	EWG CWG	2025-07-13	2025-07
Doc Date 2025-07-13 Mailing Date 2025-07 Post-Sofia Author(s) Barry Revzin, Tomasz Kamiński Target Audience EWG CWG Revisions R2 Tracking issue View on GitHub Abstract [[P3074R7] (trivial `union`s (was `std::uninitialized<T>`))](https://wg21.link/p3074r7) was adopted in Hagenberg. One of the goals of that paper was to make an example like this work:
