No, but a few ideas have been thrown around on the list in the past couple of 

Your suggestion is nice and concise - the dropping of SIGNAL() was briefly 
discussed during developed of PyQt4.

One sublety of your suggestion is that "self" provides the emitter object 
whereas the short form of the Qt connect uses "this" to provide the slot 
object. I don't know if that would be counter-intuitive.

I'd like people to continue to throw out suggestions and see if any sort of 
concensus appears. The existing method for making connections will be 
retained no matter what.
