Isn't this a very common pattern?
Yes (although you have it reversed), but that's not what we were talking about.
It's the same underlying issue, replacing const string& by string_view doesn't change it.
We were talking about this:
void f1(const string_ref&); string f2();
f1(f2());
Or this:
void f1(const string_ref&);
AFAIK string_ref should be passed by value, not by const&. -- Olaf
