The expression return new O2System\Reactor\Models\Sql\Relations\BelongsToMany(new O2System\Reactor\Models\Sql\Relations\Maps\Intermediary($this, $relationModel, $pivotTable, $foreignKey, $primaryKey))->getResult() also could return the type O2System\Reactor\Models\Sql\DataObjects\Result which is incompatible with the documented return type O2System\Reactor\Models\Sql\DataObjects\Result\Row|boolean.
