はじめに(Introduction)
N4910 Working Draft, Standard for Programming Language C++
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/n4910.pdf
n4910は、ISO/IEC JTC1 SC22 WG21の作業原案(Working Draft)です。
公式のISO/IEC 14882原本ではありません。
ISO/IEC JTC1 SC22 WG21では、可能な限り作業文書を公開し、幅広い意見を求めています。
一連の記事はコード断片をコンパイルできる形にする方法を検討してコンパイル、リンク、実行して、規格案の原文と処理系(g++, Clang++)との違いを確認し、技術内容を検討し、ISO/IEC JTC1 SC22 WG21にフィードバックするために用います。
また、CERT C++, MISRA C++等のコーディング標準のコード断片をコンパイルする際の参考にさせていただこうと考えています。CERT C++, MISRA C++が標準化の動きとの時間的なずれがあれば確認できれば幸いです。また、boostライブラリとの関連、Linux OS, TOPPERSカーネル、g++(GCC), clang++(LLVM）との関係も調査中です。
何か、抜け漏れ、耳より情報がありましたらおしらせくださると幸いです。
<この項は書きかけです。順次追記します。>
背景(back ground)
C/C++でコンパイルエラーが出ると、途方にくれることがしばしばあります。
何回かに１回は、該当するエラーが検索できます。
ただ、条件が違っていて、そこでの修正方法では目的を達成しないこともしばしばです。いろいろな条件のコンパイルエラーとその対応方法について、広く記録することによって、いつか同じエラーに遭遇した時にやくに立つことを目指しています。
この半年の間で、三度、自分のネットでの記録に助けられたことがあります。
また過去に解決できなかった記録を１０種類以上、最近になって解決できたことがあります。それは、主に次の３つの情報に基づいています。
cpprefjp - C++日本語リファレンス
コンパイラの実装状況
また
https://researchmap.jp/joub9b3my-1797580/#_1797580
に記載したサイトのお世話になっています。
作業方針(sequence)
Clang++では-std=c++03, C++2bの2種類
g++では-std=c++03, c++2bの２種類
でコンパイルし、
１）コンパイルエラーを収集する。
２）コンパイルエラーをなくす方法を検討する。
コンパイルエラーになる例を示すだけが目的のコードは、コンパイルエラーをなくすのではなく、コンパイルエラーの種類を収集するだけにする。
文法を示すのが目的のコード場合に、コンパイルエラーをなくすのに手間がかかる場合は、順次作業します。
３）リンクエラーをなくす方法を検討する。
文法を示すのが目的のコード場合に、リンクエラーをなくすのに手間がかかる場合は、順次作業します。
４）意味のある出力を作る。
コンパイル、リンクが通っても、意味のある出力を示そうとすると、コンパイル・リンクエラーが出て収拾できそうにない場合がある。順次作業します。
１）だけのものから４）まで進んだものと色々ある状態です。一歩でも前に進むご助言をお待ちしています。「検討事項」の欄に現状を記録するようにしています。

// 24.3.7 Class template array [array]
// 24.3.7.1 Overview [array.overview]
// The header <array> defines a class template for storing fixed-size sequences of objects. An array is a contiguous container (24.2.2.1). An instance of array<T, N> stores N elements of type T, so that size() == N is an invariant.
// An array is an aggregate (9.4.2) that can be list-initialized with up to N elements whose types are convertible to T.
// An array meets all of the requirements of a container (24.2.2.2) and of a reversible container (24.2.2.3), except that a default constructed array object is not empty if N > 0. An array meets some of the requirements of a sequence container (24.2.4). Descriptions are provided here only for operations on array that are not described in one of these tables and for operations where there is additional semantic information.
// array<T, N> is a structural type (13.2) if T is a structural type. Two values a1 and a2 of type array<T, N> are template-argument-equivalent (13.6) if and only if each pair of corresponding elements in a1 and a2 are template-argument-equivalent.

// 24.3.8.1 Overview [deque.overview]
// A deque is a sequence container that supports random access iterators (25.3.5.7). In addition, it supports constant time insert and erase operations at the beginning or the end; insert and erase in the middle take linear time. That is, a deque is especially optimized for pushing and popping elements at the beginning and end. Storage management is handled automatically.
// A deque meets all of the requirements of a container (24.2.2.2), of a reversible container (24.2.2.3), of an allocator-aware container (24.2.2.5), and of a sequence container, including the optional sequence container requirements (24.2.4). Descriptions are provided here only for operations on deque that are not described in one of these tables or for operations where there is additional semantic information.

// Effects: An insertion in the middle of the deque invalidates all the iterators and references to elements of the deque. An insertion at either end of the deque invalidates all the iterators to the deque, but has no effect on the validity of references to elements of the deque.
// Complexity: The complexity is linear in the number of elements inserted plus the lesser of the distances to the beginning and end of the deque. Inserting a single element at either the beginning or end of a deque always takes constant time and causes a single call to a constructor of T.
Remarks:
If an exception is thrown other than by the copy constructor, move constructor, assignment operator, or move assignment operator of T there are no effects. If an exception is thrown while inserting a single element at either end, there are no effects. Otherwise, if an exception is thrown by the move constructor of a non-Cpp17CopyInsertable T, the effects are unspecified.

An erase operation that erases neither the first element nor the last element of a deque invalidates the past-the-end iterator and all iterators and references to all the elements of the deque.
// [Note 1: pop_front and pop_back are erase operations.
Throws:
Nothing unless an exception is thrown by the assignment operator of T.
// Complexity: The number of calls to the destructor of T is the same as the number of elements erased, but the number of calls to the assignment operator of T is no more than the lesser of the number of elements before the erased elements and the number of elements after the erased elements.

// 24.3.9 Class template forward_list [forward.list]
// 24.3.9.1 Overview [forward.list.overview]
// A forward_list is a container that supports forward iterators and allows constant time insert and erase operations anywhere within the sequence, with storage management handled automatically. Fast random access to list elements is not supported.
// [Note 1: It is intended that forward_list have zero space or time overhead relative to a hand-written C-style singly linked list. Features that would conflict with that goal have been omitted. —end note]
// A forward_list meets all of the requirements of a container (24.2.2.2), except that the size() member function is not provided and operator== has linear complexity, A forward_list also meets all of the
requirements for an allocator-aware container (24.2.2.5). In addition, a forward_list provides the assign member functions and several of the optional sequence container requirements (24.2.4). Descriptions are provided here only for operations on forward_list that are not described in that table or for operations where there is additional semantic information.
// [Note 2 : Modifying any list requires access to the element preceding the first element of interest, but in a forward_list there is no constant-time way to access a preceding element. For this reason, erase_after and splice_after take fully-open ranges, not semi-open ranges. —end note]

// A vector is a sequence container that supports (amortized) constant time insert and erase operations at the end; insert and erase in the middle take linear time. Storage management is handled automatically, though hints can be given to improve efficiency.
// A vector meets all of the requirements of a container (24.2.2.2), of a reversible container (24.2.2.3), of an allocator-aware container (24.2.2.5), of a sequence container, including most of the optional sequence container requirements (24.2.4), and, for an element type other than bool, of a contiguous container (24.2.2.1). The exceptions are the push_front, prepend_range, pop_front, and emplace_front member functions, which are not provided. Descriptions are provided here only for operations on vector that are not described in one of these tables or for operations where there is additional semantic information.
// The types iterator and const_iterator meet the constexpr iterator requirements (25.3.1).
