FR281 24.04.4 Copyability of "view" P1456 #277
Description
The View concept requires copy-ability. There are reasons why this is overly restrictive - for example a predicate might not be copyable or a view might need to hold a coroutine_handle which should not be copied.
As concepts are hardly modifiable after the publication of the standard, it is important to relax this constraint while we still can
Proposed change:
Adopt P1456 which was approved by LEWG
