I think Josef specifically meant `recarrays`, which give access to
elements of a structured array via attribute access. I'd tend to agree
with him that those turned out not to be such a great idea. But (I
think) nobody is arguing we should get rid of arrays with structured
dtypes - I use them regularly myself too.
