Travis is correct.  PyFITS uses recarrays quite extensively.  It was the 
large, legacy numarray project I was referring too. ;-)

I had forgotten about the attribute access.  I know a number of people 
who use that feature in conjunction with matplotlib for plotting data in 
tables, especially during interactive use.
