other uses as soon as your C function returns. You should malloc it instead
(but you don't have to worry about free'ing it, numpy will do that when the
array object is deconstructed). Any C reference will fill you in on

Or have an opinion about it having derived the type from
collections.namedtuple? Anyone have an open-source, numpy-based
alternative? Ditto last

believe this came out of a SciPy 2011 sprint. See
