Are you sure of that? It seems that at least for AA's, empty arrays are 
different than null arrays:

	int[char[]] b;		
	writefln(b is null); // true
	writefln(b == null); // true
	
	b["hello"] = 3;
	b.remove("hello");
	
	writefln(b); // empty AA
	writefln(b is null); // false
	writefln(b == null); // false (note this line in particular)

	b = null;
	writefln(b is null); // true
	writefln(b == null); // true
