Unfortunately, there is no equivalent way to disable assignment 
of [] at compile time.

struct ArrayWrapper(T)
{
	T[] a;
	
	this(T[] arr) { a = arr; }
	
         //Doesn't work; Conflicts with this(T[] arr)
         //@disable this(typeof(this)[]);

         //Doesn't work; hijacked by this(T[] arr)
         //@disable this(typeof([]));
}
