Sorry, I can't follow you here. 1) signal and slot already take string  
arguments. This discussion is to get rid of them. 2) connect is  
already a method of QObject. Since you have to connect two objects,  
you must always pass the second one as a parameter to the  
first.connect() call.

Currently, my favorite is:

     self.connect(other.CLICKED, ....)

because that avoids typos and folds the first and second argument of  
the connect call into one argument. I'm just curious how you can split  
"other.CLICKED" into "other" and "other.__class__.CLICKED" in connect  
without losing compatibility with old code.

     self.connectClicked(other, ...)

would be more simple but it's a brain twister: clicked doesn't belong  
to self but to other.

     other.connectClicked(self.otherWasClicked)

might be the way to go.
