Rendering theme_item_list items My module provides a simple block which needs to contain an unordered list with some images. 
From a block function, I am returning a renderable array:

$block['content'] = array(
    'list' =&gt; array(
        '#theme' =&gt; 'item_list',
        '#type' =&gt; 'ul',
        '#attributes' =&gt; array('class' =&gt; 'foo1'),
        '#items' =&gt; array(
          /* ...  what should go here? */
        ),
    ),
);


I would like to have some renderable arrays as items in the item list, but I seem to be unable to insert any arrays into the #items array.

The Drupal 7 theme_item_list API docs says:


  items: An array of items to be displayed in the list. If an item is a
  string, then it is used as is. If an item is an array, then the "data"
  element of the array is used as the contents of the list item. If an
  item is an array with a "children" element, those children are
  displayed in a nested list. All other elements are treated as
  attributes of the list item element.


I tried using both "data" and "children" elements, but I get either empty &lt;li&gt;'s or there is a word Array inside them.

What is the proper way to do this? Is theme_item_list the right/up-to-date solution?
Something like this:

foreach ($images as $image) {

  // New array for readability
  $options = array(
    'path' =&gt; $image-&gt;url,
    'alt' =&gt; $image-&gt;alt,
  );

  // Push the image tag onto the items array
  $block['content']['list']['#items'][] = theme('image', $options);
}
