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.
