Where is this code from? I think I wrote something like this, but it's quite some time ago, so I forgot which issue it is. It'd be awesome if you wanted to do some support for tensors in sympy. The only example, that is known to work is the python examples/advanced/relativity.py and I just tried it and it seems to work. So that shows how to get something working, and what we need now is some general support for tensors.
