+
+$group is the name of the accessor group for the generated accessors; they
+will call get_$group($field) on get and set_$group($field, $value) on set.
+
+@fieldspec is a list of field/accessor names; if a fieldspec is a scalar
+this is used as both field and accessor name, if a listref it is expected to
+be of the form [ $accessor, $field ].
