how to generate a self::CONSTANT in an attribute

[tacman]

I'm trying to generate the following:

const PLACE_NEW = 'new';

#[Transition(from: self::PLACE_NEW)]
const TRANSITION='load';

Creating the constants is easy, but how do I create a self:: instead of the actual value? This isn't working:

            $from = 'self::PLACE_NEW'; // generates the string with self::, 
            $from = new Constant('PLACE_NEW', 'new')  // generates 'new', not self::PLACE_NEW

            $constant = $class->addConstant('TRANSITION');
            $constant->addAttribute(Transition::class, ['from' => $from]);

kinda tricky, but this library has is amazing so maybe it has something for this.
