A lot of these things were discussed at the DataArray summit they held here
a while ago, but the general push is towards being more approachable and
friendly to people who use R or do statistical data analysis on possibly
messy data. I don't use R, but I think I'm fairly good at producing things
which are both powerful and intuitive in the end, which is what I'm trying
to do here. That's my understanding of the thinking, others at Enthought
will have to correct me if I'm wrong...
