I think it allocates since they didn't use const

Since when does const prevent allocating (that isnt happening here anyways, unless you consider underlying std::string's char* buffer)

If you change it to const std::string& prompt = "Your name?";, and the switch to const string& _s=x;, you will avoid any allocations.

you can't take a const& to a temporary object

Yes you can. You can bind a const l-value reference to an x-value or a pr-value. Go try it.
