Regarding the implementation, T_OBJECT and T_DATA methods are
guaranteed not to make any asumption on the internal structure
of their objects.  So you can use T_OBJECT for Data_Wrap_Struct
instead.  A possibile plan would be removal Data class and
replacement by rb_cObject, but I can't estimate how it will
affect widely.
