OK, fair enough.

Incidentally, I realized  that this attribute
_coldefs is not part of recarray anyway, but something added by pyfits.
I see now that the names and the formats with a greater than sign
concatenated on the front can be extracted from dtype:

In [247]: t.dtype
Out[247]: [('x', '>f4'), ('y', '>i4')]

I could write my own function to extract what I need, but I thought I
would ask: is there already a simpler way?  And is there a function to
compare this '>f4' stuff to the named types such as Float32 ('f')?

Erin
P.S. If it is man power that is preventing some of the simple things
like this from being implemented, I could volunteer some time.
