Description

The following code:

// This is not working because there's no space for hash sign. This is working before.
class SignupForm extends Model
{
    public function rules()
    {
        return [
            #['username', 'string', 'min' => 7, 'max' => 12],
        ];
    }

// This is working if i put space for hash sign.
class SignupForm extends Model
{
    public function rules()
    {
        return [
            # ['username', 'string', 'min' => 7, 'max' => 12], 
        ];
    }

Resulted in this output:

Hi @ljfreelancer88. You're a few years late to the party. https://wiki.php.net/rfc/shorter_attribute_syntax_change This is expected because #[ denotes the start of an attribute.
