Doc Date 2025-06-06 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke Target Audience LEWG SG6 Revisions R4 R3 Tracking issue View on GitHub Abstract C++ currently only offers truncating integer division in the form of the `/` operator. I propose standard library functions for computing quotients and remainders with other rounding modes.

	P3737R0	std::array is a wrapper for an array!	Jan Schultke J. Schultke	LEWG	2025-06-11	2025-07
Doc Date 2025-06-11 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke Target Audience LEWG Revisions R4 R3 Tracking issue View on GitHub Abstract The `std::array` class template is implemented as a simple wrapper type for a "C-style array". However, its specification in the standard is considerably more permissive and should be simplified.
	P3740R1	Last chance to fix std::nontype	Jan Schultke J. Schultke , Bronek Kozicki B. Kozicki	LEWG	2025-06-20	2025-07
Doc Date 2025-06-20 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke, Bronek Kozicki Target Audience LEWG Revisions R0 Tracking issue View on GitHub Abstract P2472R3 introduced overloads for the `std::function_ref` constructor which utilize a helper type `std::nontype`. This helper type may be obsoleted by other active proposals, and its name has become a bad choice now that C++26 no longer replaced the term "non-type template parameter", with "constant template parameter".
	P3749R0	Slides in response to P3655R2 - Concerns regarding std::zstring_view	Jan Schultke J. Schultke	LEWG	2025-06-27	2025-07

	P3753R1	Slides for P3740R1 - Last chance to fix std::nontype	Jan Schultke J. Schultke	LEWG	2025-06-20	2025-07
Doc Date 2025-06-20 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke Target Audience LEWG Revisions R0 Tracking issue View on GitHub Abstract - P2472R3 added `std::nontype` constructors for `std::function_ref` - merged into P0792R14, plenary-approved Varna 2023 for C++26 - `std::nontype` possibly obsoleted by `std::constant_wrapper` (P2781R9) - Wording review completed by LWG - "non-type template parameter" term was removed by P2841R1 (C++26)
	P3774R0	Rename std::nontype, and make it broadly useful	Jan Schultke J. Schultke , Bronek Kozicki B. Kozicki , Tomasz Kamiński T. Kamiński	LEWG	2025-07-15	2025-07
Doc Date 2025-07-15 Mailing Date 2025-07 Post-Sofia Author(s) Jan Schultke, Bronek Kozicki, Tomasz Kamiński Target Audience LEWG Tracking issue View on GitHub Abstract [[P3740R1]](https://isocpp%2eorg/files/papers/P3740R1%2ehtml) proposed to rename `std::nontype` to `std::constant_arg`, now that the term "non-type template parameter" no longer exists in the C++26 standard. This solution found weak consensus in LEWG, but there was no time in LWG to review the change, so it did not make it into C++26.
