One to Many "InTraverse" Class

[AddoSolutions]

Let's say I have a many to many relation from posts to comments. Right now if I executed:
<?php $post->comments
I would get an array of all of the comments associated with that post.

But here is what I propose (roughly):
<?php namespace \Orm\Model class InTraverse implements \ArrayAccess{ private $_elements = array(); function __get($prop){ $children = array(); foreach ($this->_elements as $id=>$element) $children[$id] = $element->$prop return $children; } }

And so on with methods etc.

This would allow us to:

<?php $post->comments->message
and would return an array with all the messages from each comment (which can easily be imploded, used for Form::select(), etc.)

Sorry about all the updates, I accidentally submitted it before I could finish writing about the issue. This would still allow for current usage of the one to many (and many to many) functions, yet still adding a new later of flexibility to the ORM.

Thoughts?

Code up a solution and we'll have a look... For now I don't see how this is going to work.

This looks interesting, but I have used Arr:pluck() in the past to do this.

Alright, I have coded up a potential solution. This basically causes all data returned by the ORM to be passed into a class in the Orm namespace in a model-level defined class called collection.
