I often write code like this:

if(auto p = getSome())
	if(auto parent = p.getParent())
		if(auto uncle = parent.getBrother())
			uncle.doSome();

This cannot be translated into a conjunction of conditions without 
having to specify declarators before. I would not like to lose that 
possiblity.

I'm not so sure about the dangling else issue. I don't want to be 
pampered all the time, but I have to admit to have run into that issue, too.
