Mailing Date 2026-07 Post-Brno Author(s) Hana Dusíková Target Audience LEWG LWG Revisions R5 Tracking issue View on GitHub Disposition Date 2026-06 Abstract Pointer tagging is widely known and used technique ([Glasgow Haskell Compiler](https://takenobu-hs.github.io/downloads/haskell_ghc_illustrated.pdf), LLVM's `[PointerIntPair](https://github.com/llvm/llvm-project/blob/8e5aa538caccef167e8096b2173fdaf2be9cc129/llvm/include/llvm/ADT/PointerIntPair.h#L80)`, `[PointerUnion](https://github.com/llvm/llvm-project/blob/8e5aa538caccef167e8096b2173fdaf2be9cc12
	P3367R5	constexpr coroutines	H. Dusíková	CWG LWG
Mailing Date 2026-07 Post-Brno Author(s) Hana Dusíková Target Audience CWG LWG Tracking issue View on GitHub Abstract Currently C++'s [doesn't allow coroutines to be `constexpr`](https://eel.is/c++draft/dcl.constexpr#3.1). This limitation forces users to choose between having `constexpr` compatible library or (maybe) simpler coroutine interface. As a library author I do prefer `constexpr` but I do not want to make this decision.
	P3655R5	cstring_view	P. Bindels, H. Dusikova, J. Rifkin, M. Foco, A. Shevlyakov	LEWG LWG
Mailing Date 2026-07 Post-Brno Author(s) Peter Bindels, Hana Dusikova, Jeremy Rifkin, Marco Foco, Alexey Shevlyakov Target Audience LEWG LWG Revisions R4 Tracking issue View on GitHub Abstract We propose a standard string view type that guarantees null-termination.
	P3771R1	constexpr mutex, locks, and condition variable	H. Dusíková	LEWG SG1
Mailing Date 2026-07 Post-Brno Author(s) Hana Dusíková Target Audience LEWG SG1 Tracking issue View on GitHub Abstract It's really hard to conditionally avoid non-`constexpr` types in a code which is supposed to be `constexpr` compatible. This paper fixes it by making these types (and algorithms) `constexpr` compatible. There is no semantical change for updated types and algorithms.
	P3791R1	constexpr deterministic random	H. Dusíková	LWG
Mailing Date 2026-07 Post-Brno Author(s) Hana Dusíková Target Audience LWG Tracking issue View on GitHub Abstract Algorithms `shuffle`, `sample` are useful even in compile time, same applies to random distribution types which are fully deterministic.
	P4148R2	protocol: Structural Subtyping for C++	J. Coe, H. Dusikova, A. Peacock, P. Craig, N. Banglawala	LEWGI
Mailing Date 2026-07 Post-Brno Author(s) Jonathan B. Coe, Hana Dusikova, Antony Peacock, Philip Craig, Neelofer Banglawala Target Audience LEWGI Revisions R1 R0 Tracking issue View on GitHub Abstract We propose `protocol<T,` `A>` and `protocol_view<T>`, standard library vocabulary types for structural subtyping in C++. Interfaces are specified as plain structs; any type whose member functions satisfy the interface is accepted without requiring explicit inheritance.
