Unexpected value conversion when using an abstract class with type param

[deepcake]

Discovered a value conversion when using an abstract class with a type param (not sure what exactly causes this behavior). If you make the dispatch method inline, it will work as expected. <Int> is also converted - it prints 1074069696 no matter what value is passed.

class Test {
  static function main() {
    var s = new Signal1<Bool>();
    s.add(cb);
    s.dispatch(false); // <--- Test.hx:8: true
  }
  static function cb(v:Bool) {
    trace(v);
  }
}

@:forward(length, iterator)
abstract Signal1<T>(Array<T->Void>) {
  public inline function new() {
    this = new Array<T->Void>();
  }
  public inline function add(cb:T->Void) {
    this.push(cb);
  }
  public function dispatch(value:T) {
    for (cb in this) {
      cb(value);
    }
  }
}
