FYI, there was some good discussion on labeled arrays at SciPy
conference, since there are about 7 different implementations of this
idea right now. Fernando has worked on an implementation that's here
and was very interested to see if larry and pandas could be made to
work on top of an implementation like this.

If you go into docs and build the documentation there is a
basic_data_array.html that goes through the implementation. It's pure
python at this point.
There will be a discussion on the mailing list soon, so I just wanted
to make sure you got a heads up for comments since you weren't here.
