Editorial changes

• Replaced PDTS on the front page with TS.
• Proposed wording for issue 15 missed adding constexpr to declarations of comparison operators in synopsis. Fixed by adding constexpr to the declarations in synopsis.
• Fixed typo in resolution of issue 23: "coroutine_handle<Promise<" => "coroutine_handle<Promise>".
• Moved example from paragraph 8.4.4/12 to paragraph 8.4.4/8 where it belongs. A year ago paragraph 12 was reordered to be paragraph 8, but the related example was not moved and stayed attached to the wrong paragraph. Fixed now.

  • A program may specialize this template. Such specialization shall define a publicly accessible nested type named \tcode{promise_type}.
    to
  • All specializations of this template shall define a publicly accessible nested type named \tcode{promise_type}.
• Reworded 18.11.2/2 from:
  • The behavior of a program that adds specializations for \tcode{coroutine_handle} is undefined.
    to
  • If a program declares an explicit or partial specialization of \tcode{coroutine_handle}, the behavior is undefined.
