Yes.  But I think it's better for T_DATA object to use
Data_Make_Struct/Data_Wrap_Struct, as Clemens stated.

I made several classes to call `initialize', such as Array, Range,
Dir, etc.  But still wondering whether *every* class calls `initialize'
or not, for cases the arguments to `new' used for allocation.
