[TYPO3-mvc] Use index of iteration attribute as array index

[Dmitri Pisarev]

I have added another function to my Article model class as this:
	/**
	 * Constructs the wrapper object for images and their captions
	 *
	 * @return array() $imagesWithCaptions
	 */
	public function getImagesWithCaptions() {
		$captions = $this->getCaptions();
		foreach ($this->getImages() as $key => $image) {
			$array[$key]['image'] = $image;
			$array[$key]['caption'] = $captions[$key];
		}
		return $array;
	}
now I can use article.imagesWithCaptions and it works just fine.

I always had A QUESTION: is using such faux getters is a valid design 
pattern?

Regards,
Dmitri.
