--- Comment #1 from 康桓瑋 <hewillk at gmail dot com> ---
#include <utility>
namespace std {
constexpr size_t dynamic_extent = -1;
template<class IndexType, size_t... Extents>
class extents { };
template<class IndexType, size_t Rank>
using dextents = decltype([]<size_t... Is>(index_sequence<Is...>) {
return extents<IndexType, ((void)Is, dynamic_extent)...>{};
}(make_index_sequence<Rank>{}));
// this works well
static_assert(std::is_same_v<
dextents<int, 3>,
extents<int, dynamic_extent, dynamic_extent, dynamic_extent>>
);
template<class ElementType, class Extents>
class mdspan {
template<class Ptr, class... Integrals>
explicit mdspan(Ptr ptr, Integrals... exts);
};
template<class ElementType, class... Integrals>
explicit mdspan(ElementType*, Integrals...)
->mdspan<ElementType, dextents<size_t, sizeof...(Integrals)>>;
}

This looks like another one of the lamdba inside a decltype for a type alias
issues.

Fixed on the trunk for GCC 14 by the recent lambda template patches.
