_value is fine IMO. You can have
vector<polymorphic_value<Shape>> v;
and then
v.push_back( Circle(10) );
v.push_back( Ellipse(10, 15) );
v.push_back( Square(11) );
I would drop the U* constructor though. It's a remnant of the times this was
called a pointer. U&& is all that's needed.
It's unfortunate we have to use -> instead of . but that's what's available.
