I know we're planning to discuss at SciPy in Austin and will hopefully
have a gameplan. We should coordinate the discussions / implementation
somewhere. I've implemented some groupby functionality in pandas but I
guess at a higher level than what's been proposed to add to NumPy.
On the pystatsmodels mailing list we've been starting to have some
discussions about statistically-oriented data structures in general--
I'll be sending an e-mail to the NumPy mailing list soon to start a
broader discussion which will hopefully lead to some good things at
