.phpstorm.meta.php: Autocomplete method argument with object properties

Hi,

Using PHPStorm Meta, is there any way to get a method argument autocompleted with a list of object properties ?

For example, having this class:

class Foo
{
  public $a;
  public $b;
  public $c;

  public function doSomething($attr) {
    // ...
  }
}

$foo = new Foo();
$foo->doSomething('<caret>');

Is there a way to get "a", "b" and "c" suggested at caret?

Thank you.
