I knew I shouldn't get dragged into this. :)
The problems with the current situation are well-documented. Every
Python book introduces this feature with a statement along the lines of:
"this is something that's going to be different than you expect...be
careful." It is one of Guido's oldest regrets. Arguing about it isn't
really going to change anything. Either someone will step up and do the
implementation, in which case the behaviour likely will change, as Guido
wants it to, or nobody ever will, in which case the status quo will

I'll take that as a vote in favor of PEP 240. :)
