個人開発と読書感想文に焦点を当てたのは良い企画だと思った。
<この項は書きかけです。順次追記します。>
読書感想文
CコンパイラによるC言語規格の読書感想文として掲載しています。
コンパイル実験が、C++N4910に対する、G++とClang++による感想文だということご理解いただけると幸いです。
読書感想文は人間かAIだけが作るものとは限りません。
本（電子書籍を含む）を入力として、その内容に対する文字列を読書感想文として受け止めましょう。
元の文章をあり方、コンパイルできるように電子化しておくこと、コンパイラが解釈可能な断片の作り方など。

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
C++ 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 のWG21を含むいくつかのWG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。
ISO/IEC JTC1 SC7からISO/IEC JTC1 SC22リエゾンとして、2000年頃、C/C++の品質向上に貢献しようとした活動をしていたことがあります。その頃は、まだISO/IEC TS 17961の原案が出る前です。Cの精神が優勢で、セキュリティ対策は補助的な位置付けでした。ISO/IEC TS 17961の制定と、C/C++のライブラリ類の見直しと、C++の進化はどんどん進んでいきます。
進化の具合が、どちらに行こうとしているかは、コンパイルて実行させてみないとわかりません。C/C++の規格案の電子ファイルは、そのままコンパイルできる形式であるとよいと主張してきました。MISRA-C/C++, CERTC/C++でも同様です。MISRA-C/C++は、Example Suiteという形で、コード断片をコンパイルできる形で提供するようになりました。
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, 箱庭プロジェクト、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。
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。

// Class template basic_syncbuf stores character data written to it, known as the associated output, into internal buffers allocated using the object’s allocator. The associated output is transferred to the wrapped stream buffer object *wrapped when emit() is called or when the basic_syncbuf object is destroyed. Such transfers are atomic with respect to transfers by other basic_syncbuf objects with the same wrapped stream buffer object.
// 31.11.2.2 Construction and destruction [syncstream.syncbuf.cons]
basic_syncbuf(streambuf_type* obuf, const Allocator& allocator);
// Effects: Sets wrapped to obuf.
// Postconditions: get_wrapped() == obuf and get_allocator() == allocator are true.
// Throws: Nothing unless an exception is thrown by the construction of a mutex or by memory allocation.
// Remarks: A copy of allocator is used to allocate memory for internal buffers holding the associated output.
basic_syncbuf(basic_syncbuf&& other);
// Postconditions: The value returned by this->get_wrapped() is the value returned by other.get_- wrapped() prior to calling this constructor. Output stored in other prior to calling this constructor will be stored in *this afterwards. other.pbase() == other.pptr() and other.get_wrapped() == nullptr are true.
// Remarks: This constructor disassociates other from its wrapped stream buffer, ensuring destruction of other produces no output.
~basic_syncbuf();
// Effects: Calls emit().
// Throws: Nothing. If an exception is thrown from emit(), the destructor catches and ignores that exception.
// 31.11.2.3 Assignment and swap [syncstream.syncbuf.assign]
basic_syncbuf& operator=(basic_syncbuf&& rhs);
// Effects: Calls emit() then move assigns from rhs. After the move assignment *this has the observable state it would have had if it had been move constructed from rhs (31.11.2.2).
// Postconditions: — rhs.get_wrapped() == nullptr is true.
// — this->get_allocator() == rhs.get_allocator() is true when allocator_traits<Allocator>::propagate_on_container_move_assignment::value is true; otherwise, the allocator is unchanged. Returns: *this.
// Remarks: This assignment operator disassociates rhs from its wrapped stream buffer, ensuring destruction of rhs produces no output.
void swap(basic_syncbuf& other);
// Preconditions: Either allocator_traits<Allocator>::propagate_on_container_swap::value is true or this->get_allocator() == other.get_allocator() is true.
// Effects: Exchanges the state of *this and other.
// 31.11.2.4 Member functions [syncstream.syncbuf.members]
bool emit();
// Effects: Atomically transfers the associated output of *this to the stream buffer *wrapped, so that it appears in the output stream as a contiguous sequence of characters. wrapped->pubsync() is called if and only if a call was made to sync() since the most recent call to emit(), if any.
// Synchronization: All emit() calls transferring characters to the same stream buffer object appear to execute in a total order consistent with the “happens before” relation (6.9.2.2), where each emit() call synchronizes with subsequent emit() calls in that total order.
// Postconditions: On success, the associated output is empty.
// Returns: true if all of the following conditions hold; otherwise false:
// — wrapped == nullptr is false.
// — All of the characters in the associated output were successfully transferred. —
// The call to wrapped->pubsync() (if any) succeeded.
// Remarks: May call member functions of wrapped while holding a lock uniquely associated with wrapped. streambuf_type* get_wrapped() const noexcept;
// Returns: wrapped.
allocator_type get_allocator() const noexcept;
// Returns: A copy of the allocator that was set in the constructor or assignment operator.
void set_emit_on_sync(bool b) noexcept;
// Effects: emit_on_sync = b.
// 31.11.2.5 Overridden virtual functions [syncstream.syncbuf.virtuals]
int sync() override;
// Effects: Records that the wrapped stream buffer is to be flushed. Then, if emit_on_sync is true, calls emit().
// [Note 1: If emit_on_sync is false, the actual flush is delayed until a call to emit(). —end note] Returns: If emit() was called and returned false, returns -1; otherwise 0.
// 31.11.2.6 Specialized algorithms [syncstream.syncbuf.special]
template<class charT, class traits, class Allocator>
void swap(basic_syncbuf<charT, traits, Allocator>& a,

// 31.11.3.3 Member functions [syncstream.osyncstream.members]
void emit();
// Effects: Behaves as an unformatted output function (31.7.5.4). After constructing a sentry object, calls sb.emit(). If that call returns false, calls setstate(ios_base::badbit).

ここでコンパイルしたコードと同じようなコードを使っているか、
ここで出たコンパイルエラーと同じようなエラーがでたかを
いろいろな版のコンパイラでコンパイルして確認していく。
この項目は、箱庭プロジェクトを市場分析の対象として、原則的には、箱庭プロジェクトの外部から分析し、外部から箱庭の広告宣伝のための戦略会議を仮想した結果、仮想「箱庭もくもく会」を開催してみることを企画するものである。

４月以降、せっせとリンクリストを作り、統計を取って確率を説明しようとしている。
2025年２月末を目標にしている。
