Great. I've just experimented about ways to connect signals yesterday :)
I also used with-objects macro, after comparing with C++ version and also
looking at the macro's source code. I think the spirit is: if the C++
version used a local object (implicit object construction and destroying),
use with-objects; but if the C++ version used a pointer without deleting
it, don't use with-objects. Correct me if I'm wrong, and I think this
information is quite useful for new CommonQt users if you add it to the
documentation.

Another interesting thing is QVector's streaming operator:

QPolygon polygon;
polygon << QPoint(10, 20) << QPoint(20, 30);

Of course it's not mandatory to use "<<" but it's convenient. Just curious:
can we do it similarly in CommonQt?

BTW: I'm talking about this because I use QPolygon in my project. It uses
QGraphicsView heavily and everything is going on very well.
