Well, I guess it is exactly the "not explicit enough" thing, at least
when related to the case I described:

Foo foo()
{
 return Foo( ...... );
}

Foo( ..... ) is a full expression rather than subexpression. So, is the
implementation _required_ to instantiate _this_ temporary under the
current standard?
