1, you can implement multiple interfaces
2, you may want to return object instead of extending classes,
eg.
class Small_Class_Abstract
{
public function getFormGeneration()
{
return new Form_Generation();
}
}
class Small_Class_A extends Small_Class_Abstract
{
}
$A = new Small_Class_A();
$form = $A->getFormGeneration()->newForm();
