--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
(In reply to Will Wray from comment #2)
> Would an early-delivered future feature require an opt-in switch?

The relevant -std switch would be the opt-in.

> Can P1061 be default enabled under earlier std flags by DR or otherwise?

Not as a DR, absolutely not. There is no defect.

It could be supported in non-strict modes as an extension, if the syntax
doesn't conflict with anything a valid program would use.=
