Subject: attr_reader, default attribute value, and rdoc of attribute

What I want to do is create an attribute, allow it to have a default
value, and have the attribute documented as such (and not as a method)
with rdoc.  So, would the proper syntax for accomplishing this
elementary feat be:

   # Field (row) delimiter.  Default is a comma.
   attr_reader fld_delimiter

   # :call-seq:
    #   fld_delimiter
    #
    # Returns the field (column) delimiter.  Default is comma.
    def fld_delimiter #:nodoc:
      !@fld_delimiter.nil? ? @fld_delimiter : (@fld_delimiter = ',')
    end

    # :call-seq:
    #   fld_delimiter(String)
    #
    # Assign a field (column) delimiter.
    def fld_delimiter=(d)
      @fld_delimiter = d
    end

 Thanks for your suggestions.
