Experiment to see if Class objects can point to interfaces. It does work!

InterfacePointerExperiment.as

package
{
	import flash.display.Sprite;

	public class InterfacePointerExperiment extends Sprite
	{
		public function InterfacePointerExperiment()
		{
			var clsA:Class = IExample;
			var clsB:Class = IExample;

			if (clsA == clsB)
			{
				trace("Comparing two Class objects pointing to the same Interface is possible!");
			}

			if (clsA == IExample)
			{
				trace("Comparing a Class object to the direct Interface is possible!");
			}
		}
	}
}

interface IExample
{
}
