Yii have helper/component debug class available everywhere with simple syntax and without having to import

Let's say I have the Debug helper with a method to display a variable's content in a way similar to this:

namespace app\components;

class D extends \yii\base\Component
{
    public static function trace($variable='')
    {
        echo $variable;
    }

}

Is there a way for this component to be available in any Controller, Model and View by using its simple form and simply write:

D::trace($bob);

I would like to know if it's possible to import it everywhere so I wouldn't have to use one of these

// Load in config then use this (too long)
Yii::$app->D->trace($key);

// Write the whole namespace everytime (too long)
\app\components\D::trace($value);

// Load the namespace first every time I need it first (Annoying)
use app\components\D;
D::trace($value);

You have two choices:

  1. Create helper in global namespace and add leading slash everywhere:

    \D::trace($value);

  2. Create global function as a wrapper for helper (or its methods):

    function d() {
    static $d;
    if ($d === null) {
        $d = new D();
    }

    return $d;
}

d()->trace($string)

    or

    function dtrace($string) {
    return D::trace($string);
}

dtrace($string);
