Those errors can be caught at compile time if class "basic_string_ref" defintion would contain lines like following:

template<typename Allocator> basic_string_ref(std::basic_string &&) = delete;

I cannot understant does it prevent any correct usage of string_ref?

+1. I can't think of a good reason to allow this.

It would mean that string_ref will no longer compile under C++03. [ But it can certainly be done for C++11 and later ] — Marshall
