Is there autocasting for esri/Viewpoint? Is there a list of module that could be autocasted?

Can you autocast Viewpoint?

Out of curiosity, I tried to create a new Viewpoint for the home widget.

homeWidget.viewpoint = {targetGeometry: fullExtent};

And it seems to work. I tried looking through the API but I couldn't find any documentation. Is there a full list of what modules can be autocasted?
