template< bool Const >
class /*sentinel*/; // exposition only
(since C++20)

The return type of elements_view::end when the underlying view is not a common_range.

The type /*sentinel*/<true> is returned by the const-qualified overload. The type /*sentinel*/<false> is returned by the non-const-qualified overload.

The name of this class template (shown here as /*sentinel*/) is unspecified.

Typical implementation holds only one data member: a sentinel end_ obtained from (possibly const-qualified) V.
