If you could pass "this" by value instead of ref, it'd solve the 
problem nicely:

	struct MyRange {
		MyRange opSlice(int, int) @byvalue;
		void length(int) @property;
	}

Here you can call opSlice on a lvalue since it takes the "this" 
argument by value, but you can't call length(int) because it takes it 
by ref.
