Like Robert said, you still have a structured array (named fields), but not a recarray (where fields can be accessed as attributes). Use a simple .view(np.recarray) or .view(np.ma.MaskedRecords) to get the field-as-attributes behavior, if you really need it.

Because I'm still unsure whether they're completely baked. You mentioned that the defaults may not be consistent, that's one of the aspects we need to investigate further, along with testing, proper docs...
