swfsprite::add() adds a swfshape(), a swfbutton(), a swftext(), a swfaction() or a swfsprite() object.
For displayable types ( swfshape(), swfbutton(), swftext(), swfaction() or swfsprite()), this returns a handle to the object in a display list.

Apparently this function DOES, in fact, return a value as many of the MING examples show. It is a SWFDisplayItem. Here is an excerpt of an example that appears elsewhere in the MING docs...
<?php
$p = new SWFSprite();
$i = $p->add($s);
$p->nextFrame();
$i->rotate(15);
$p->nextFrame();
?>
