Exactly, Indexed is very fresh, and will probably change a bit before
the 0.7 release. See issue 2059 for instance. But as smichr figured
out in issue 2058, the .atoms() method works as it should. The
confusion comes from the fact that when an Indexed object recieves
indices, the returned object is of type IndexedElement. So you need to
use .atoms(IndexedElement)
It is very cool that you have started to use the tensor module,
Nicholas! And even cooler that you communicate the issues you have, so
that we can fix it before the next release :-)

Thanks, Oyvind; I will give it a try and let the list know how I am
doing. I find that it is quite exciting to be able to do these very
interesting (and powerful) things with sympy.
