Description:
------------
Type Hinting is compatible with array and objects, but not with array containing ONLY instances of single chosen class (array of instances). This would be appreciated, if relevant with the structure of arrays.

Reproduce code:
---------------
class B {
  public $field;
  public __construct ($param) { $this->field = $param; }
}

class A {
  public function method (B[] $parameters){
    foreach ($parameters as $object) {
      echo $object->field . "\n";
    }
  }
}

$b = Array ();
for ($count=0; $count<10; $count++) {
  $b[] = new B ($count);
}

$a = new A ();
$a->method ($b);

Expected result:
----------------
0
1
2
3
4
5
6
7
8
9

Actual result:
--------------
Parse error: syntax error, unexpected '[', expecting '&' or T_VARIABLE in __FILE__ on line __LINE__
