View all issues with WP status.
The conversion constructor of take_while_view::sentinel requires sentinel_t<V> must satisfy convertible_to<sentinel_t<Base>>, which indicates that the rvalue reference of sentinel_t<V> can be converted to sentinel_t<Base>, but in the Effects element, we assign the lvalue s.end_ to end_.
