Exactly, it's like returning a string_view from a function - which you should never do, at least not without an obvious indication...

My primary objection to this line of thinking is that the standard begin/end functions have the same dangerous implications as this function does. The input can be a string and the output is something that becomes invalid when that string is destroyed.

begin/end don't have this problem in practice because you need to call both, and that's hard to do on the same temporary. c_str does, but virtually nobody makes this mistake for some reason.
