GB-110 26.2 [ranges.syn] New views should be freestanding (repeat, stride, cartesian_product) #439
Description
The editorial instruction in P1642R11 (freestanding utilities etc) to make "everything in <ranges> except [...]" only applied to what had already been approved by LWG. Some new range adaptors approved at the same meeting as P1642R11 were reviewed later, and so were not marked freestanding. They should be freestanding though. This applies to views::repeat (P2474R2), views::stride (P1899R3), and views::cartesian_product (P2374R4).
In the <ranges> synopsis, add "freestanding" comments to repeat_view, views::repeat, stride_view, views::stride, cartesian_product_view, and views::cartesian_product.
