You've defined an attr_writer for :paralist, but need an attr_reader for it
in order for the method you are calling to be defined. You probably want to
change attr_writer to attr_reader, or use attr_accessor if you really want
it to still be writable. attr_writer defines a separate method called
paralist=. You can call that method using paraclass.paralist = foobar.
