[TYPO3-dev] Possible RFC : Introducing ARRAY_LOOP cObject

Good point.

I tried to support Traversable but the problem is the object is 
processed too by tslib_content and at some stage ->data is used as an 
array and this crashes everything.

Best for those case is, as developer, to transform the iterator into an 
array using PHP built-in method:

class MyIterator implements Iterator {
	// stuff
}

pibase:

$this->cObj->start(iterator_to_array(new MyIterator(), TRUE));

and then it works as expected.

I started a bug tracker entry: http://bugs.typo3.org/view.php?id=17420. 
I suggest to further discuss this, having patch in BT and when we agree 
this is "ready", I'll post it to the core list. There is no point 
sending an RFC there which is not production-ready.
