Re: c++ "with" keyword

[Erik Schnetter <schnetter at uni-tuebingen dot de>]

The example

	struct S
	{
	    int x;
	    int y;
	};
	
	int main()
	{
	    S s;
	    with (s)
	    {
	        .x = 1;
	        .y = 2;
	    }
	    return 0;
	}

can easily be rewritten by introducing temporary references, as in

	int main()
	{
	    S s;
	    {
	        S& t = s;
	        t.x = 1;
	        t.y = 2;
	    }
	    return 0;
	}

This requires only one additional variable reference each time the 
"with" object is used.  Additionally, it allows several "with" objects 
(with different names) at the same time.  In C, the same thing can be 
done by using pointers.
