The only problem I have with the new syntax is it doesn't handle the 
case when the slot require more arguments than the signal but the extra 
arguments in the slot are all default arguments.

For example, I can't connect my signal showMessage(QString) to 
QStatusBar::showMessage(QString, int=0) this way. I'll get a static 
assert "The slot requires more arguments than the signal provides."
