CWG388 ====== Has a note that says: This resolution would require an ABI change and was thus deferred for further consideration. No updates after that. CWG1282 ======= Proposed resolution says: An implicitly declared special member function (Clause 12 [special]) shall havehas an exception-specification But text says: An inheriting constructor ([class.inhctor]) and an implicitly declared special member function... So I used "have" instead of "has."
