Hello Hui,

I like your proposal.
One question though: Can you imagine a use case of creating a
std::ranges::single_view<TYPE>, where TYPE does not satisfy
std::move_constructible, yet it would be useful to create a
std::ranges::single_view of it?
Personally, I can't. But if there would be such a use case then I would
propose to relax the requirements on the template argument for
single_view even further:

|template<|class| T> requires is_object_v<T> class single_view;|


Best regards
Kilian
