Sure, but it is occasionally useful, especially when creating classes
that have many optional "initialization" parameters. Here's the
traditional-styled version. I use "setter" for lack of a better word.

#   attr_setter :a
#
# _is equivalent to_
#
#   def a(*args)
#     if args.size > 0
#       @a = args[0]
#       self
  #     else
  #       @a
  #     end
  #   end
