The idea is that fun(5) would be lowered to:

I don't think that lowering is recommended - it prolongs the lifetime of
the temporary through the end of the caller. But that may be actually a
good thing.
On second thought - Walter's lowering, which makes the rvalue last more
than strictly necessary, may be the most flexible of all at the cost of
more resource consumption (for types that define destructors). -- Andrei
