This is an unofficial snapshot of the ISO/IEC JTC1 SC22 WG21 Core Issues List revision 112c. See http://www.open-std.org/jtc1/sc22/wg21/ for the official list.
[Accepted at the February, 2023 meeting.]
Constructors are not intended to have explicit object parameters, but the standard is missing a corresponding prohibition.
Proposed resolution (approved by CWG 2023-01-06):
Add a new paragraph after 22.214.171.124 [class.ctor.general] paragraph 7 as follows:
A constructor shall not be a coroutine.
A constructor shall not have an explicit object parameter (126.96.36.199 [dcl.fct]).
