Hooks: separate model hooks from collection hooks

[enov]

Currently we have the following hooks:

Main API	Interface	Method
Loading	Interface_Aurora_Hook_Before_Load	before_load(&$params)
Loading	Interface_Aurora_Hook_After_Load	after_load($model_or_collection)
Saving	Interface_Aurora_Hook_Before_Save	before_save($model_or_collection)
Saving	Interface_Aurora_Hook_After_Save	after_save($model_or_collection)
Saving (create)	Interface_Aurora_Hook_Before_Create	before_create($model)
Saving (create)	Interface_Aurora_Hook_After_Create	after_create($model)
Saving (update)	Interface_Aurora_Hook_Before_Update	before_update($model)
Saving (update)	Interface_Aurora_Hook_After_Update	after_update($model)
Deleting	Interface_Aurora_Hook_Before_Delete	before_delete($model_or_collection)
Deleting	Interface_Aurora_Hook_After_Delete	after_delete($model_or_collection)

Now, every time I want to implement an after load hook, I see myself doing this:

    public function after_load($model_or_collection) {
        if (Au::type()->is_collection($model_or_collection)) {

            // either loop through it
            foreach ($model_or_collection as $model) {
                $this->after_load($model);
            }

            // or silently return;
            return;
        }

        // it's a model now, change variable name
        // for the sake of readability
        $model = $model_or_collection;
        ...
}

So I am thinking of separating the hooks for models and collections. I hope to have two separate hooks for each case, something like:

    public function after_load_model($model);
    public function after_load_collection($collection);
