But are you speaking in general or for the sake of the test? :-)
Because in the latter case it's quite obvious. In the former, this is
a better argument to disagree with my disagreement: suppose the
function f() is in a pre-compiled library. Now, go down to the
implementation level and think of the possible calling conventions

   class A {};
   A f();
   A a = f();

That begins to be off-topic though (and beyond the scope of the
standard), so I will not go on.

Genny.
