Description:
------------
Suggestion is to support foreach() to iterate actoss multidimensional arrays.

Given a higher-order array, it would be very useful to be able to collapse nested foreach statements into a single one. To exemplify:

given
$A[1][1]="A";
$A[1][2]="B";
$A[1][3]="C";
$A[2][1]="D";
etc.

foreach($A as $L1,$L2 => $V) {
  // first iteration  -- $L1=1, $L2=1, $V="A"
  // second iteration -- $L1=1, $L2=2, $V="B"
  // third iteration  -- $L1=1, $L2=3, $V="C"
  // fourth iteration -- $L1=2, $L2=1, $V="D"
}

I would have many uses for such a construct, and I'm hoping that I would not be alone.
