Support Array Operator Overloading

A DESCRIPTION OF THE PROBLEM :
It would be nice if objects (like ByteBuffer) could implement array operator overloading.
This way ByteBuffers could be a drop-in replacement for standard arrays making it easy to switch between normal arrays and ByteBuffers acting as arrays.
I'm sure other objects would benefit from this as well.

Maybe a special interface could be created that would require a getter/setter methods.

class ByteBuffer implements ArrayOperator<byte> {
  public byte get(int idx) {return ...;}
  public void set(int idx, byte value) { ... }
};

Then the following would be allowed:

ByteBuffer bb = ByteBuffer.alloc(1024);
bb[123] = 123;

Thanks,
