P1450R1 Type Modification Traits

Champion: Vincent Reverdy

Minute Taker: Chris Kennelly

Start Overview: 13:15

Start Discussion: 13:29

Think of this as a sushi menu, order what you want.

Eric:

• Qualifiers copy minus extent, all_extents, signed, pointer, all_pointer
• Qualifiers cloning minus extent, all_extents, signed, pointer, all_pointer
• Want copy_cvref

Jonathan W: Want copy_cv

Corentin: No copy_signedness

+1 remove_all_pointers

If we want copy_cv and copy_cvref, we probably want copy_const and copy_volatile.

Maybe copy_pointer is fine?

I think we want D1450R0 minus copy_signedness, **, and clone*.

Start Polling: 13:39

POLL: We want copy_all_pointers

POLL: We should promise more committee time to pursuing the subset of D1450R1 listed above and forward it to LEWG for C++23, knowing that our time is scarce and this will leave less time for other work.
