Since a string literal is considered an lvalue, why must the binding lvalue reference be const?

Question

I know there are topics that are similar to this one already (such as this).

The example given in this topic was this:

std::string & rs1 = std::strin         


        

Answer 1

The string literal may be an lvalue, but it's not a string object. There's a temporary string being created which is an rvalue.
