i do.  nice approach (row_factory) btw.

me neither - note that a 'require "arrayfields"' adds only one method to Array
though - an Array __object__ is exteneded with ArrayFields __only__ if the
fields are set.  eg

   require 'arrayfields'

   a = 0, 1, 2
   a.fields = %( zero one two )

   b = 0, 1, 2

here b has only a 'fields=' method in addition to regular Array methods.  a
has all the ArrayFields behaviour.  but maybe you probably knew that... ;-)
