				To use the notation,of course, only makes sense if you use it multiple times. Normally, you would introduce more than one int variable instead of an int-array (so using the int-array is already kind of a shorthand notation).<br />
<br />
I really have no idea what you mean with 'how such notation works with loops, shift and rotate operations'. At the moment, these operations are not defined on index-arrays, if that is what you are implying. But, that is an interesting feature one might think about. Since an index-array always represents a flattened index in the corresponding flat array by multiplying with the dimension sizes, an algebra for such int-arrays could be thought defined. <br />
<br />
Anyway, at the moment, the standard does not concern itself with that, the only operation allowed as shorthand is the index-operation itself.			</td>
