After upgrading to MooTools, 1.4.2, I noticed my charts have stopped working. The error that gets thrown, "item.$family is not a function", I have tracked to line 44 of the MooTools Core:

`if (item.$family != null) return item.$family();`

This starts from the following block within the `animate()` method call:

```
// define and run the effect
effect = new Fx.Morph(
isSVGElement ? el : $(el),
$extend({
transition: Fx.Transitions.Quad.easeInOut
}, options)
);
