--- Comment #1 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Diagnostics for ill-formed calls to adaptor pipelines regress similarly:
#include <ranges>
int main() {
extern int x[100];
(std::views::join | std::views::join)(x);
}
<stdin>: In function ‘int main()’:
<stdin>:5:40: error: use of deleted function ‘constexpr auto
std::ranges::views::__adaptor::_Pipe<_Lhs, _Rhs>::operator()(_Range&&) const &&
[with _Range = int (&)[100]; _Lhs = std::ranges::views::_Join; _Rhs =
std::ranges::views::_Join]’
