Howdy!  I just wanted to voice my agreement with this statment by Erin Sheldon:

Sometimes a['name'], sometimes a.field('name').  I vastly prefer the first 
version; it has become my favored way of dealing with my FITS and ASCII 
data.  But using the bracket notation sometimes gives an error, and I 
haven't quite figured out what the circumstances are.

Also, "for name in a.dtype.fields:" or "for name in a.fields:" would be 
very, very handy.

Could this sort of thing get put in before the beta (or is it already in, 
and I missed the boat, again?).

Thanks
John
