http://open-std.org/jtc1/sc22/wg21/docs/papers/2022/n4910.pdf を見てます (もっと正確に書くと cplusplus/draft から自分でビルドしたのを見てました)。N4901 と N4910 で番号が似ているのでややこしいですが... |

inlineを指定する前に変数定義をして後出しで inline を指定するのは文法違 反ではなく意味論違反であり、不適格である [1]。 [1] N4910 [dcl.inline]/5

元の記述だと一つの翻訳単位(C++20では正確には定義ドメイン)でインライン が指定されていれば全ての翻訳単位でインラインが暗黙に指定されるかのよう に読めるが、規格 [1] を読む限りは同変数を宣言する全ての翻訳単位で inline を明示的に指定する必要がある。 [1] N4910 [dcl.inline]/5 Co-authored-by: Kazutoshi SATODA <k_satoda@f2.dion.ne.jp>
