Simplifying the use of ref qualifiers in c++20

#include <string>

struct S
{
    std::string s_;

    std::string_view get() const &
    {
        return s_;
    }

    std::string_view get() const && = delete;
};

//  I can't change this
struct T
{
    T(std::string_view const sv);  //  does something safe with sv
};

//  I can't change this
void f(std::string_view const &);

void g()
{
    f(S{}.get());  //  should compile
    T t(S{}.get());  //  should compile
    std::string_view sv = S{}.get();  //  sh开发者_运维技巧ould not compile
}

Is there way to use ref qualifiers without hindering usability as in the case above? In essence, it should prevent unsafe usage, but allow safe usage. I can wrap f which does this, but it is unnecessary verbosity

No, because when you wrote std::string_view get() const && = delete; you're essentially(implicitly) saying that S{}.get() should not be compiled. But then later in the code you're writing f(S{}.get()); // should compile which contradicts the above code.

Basically, whether or not S{}.get() can be used is decided by the presence of the std::string_view get() const && = delete;.
