I'm not sure about the JustWorks(R)(TM), but I just created a page on the Wiki 
describing a simple example of InfoArray class
http://www.scipy.org/Subclasses
That should do what you want, but let me know if you have some more specific 
requests.
I guess I should go more into the details of subclassing on that page, but I'm 
quite far from being a specialist...
