class Builder
{
    use Traits\Builder;

    /**

    public function __construct(NodeInterface $node = null)
    {
        $this->setNode($node ?: $this->nodeInstanceByValue());

It seems like $node ?: $this->nodeInstanceByValue() can also be of type Mbh\Tree\Traits\Node; however, parameter $node of Mbh\Tree\Builder::setNode() does only seem to accept Mbh\Tree\Interfaces\Node, maybe add an additional type check?
