Multidimensional RecArrays? Nice!. Is part of the code already in CVS?

Thanks for the examples. That has clarified *a lot* where to find the
interesting data: it's clear now that what I need is _strides[0] (because I
need to access elements in a column sequentially). And that even works for
forthcoming multidimensional RecArrays which is good.
