Somewhat.

I do have some code I wrote that allows to do the compile-time argument 
checking and casting, as well as the delivery code. I know Olivier has been 
doing some experiments with connecting to regular function pointers. Put the 
two together and you've got C++0x connects.

This doesn't need to be in Qt 5.0, though.

However, the change of "signals" to public needs to. Otherwise, you cannot 
write:

	QObject::connect(sender, &SenderClass::signalName, 
		[](int i){ qDebug() << i; });

Unless you're a friend of SenderClass.
