  I have the feeling that MyInt32-only support should be enough for the
  NumArray subclass (it's a uniform array).  However, the RecArray
  subclass should be able to handle all existing types in addition to
  MyInt32.

  Hehe, it will be production code with time-critical requirements. :)
  However, it now seems to me that subclassing NumArray and RecArray
  will be the right thing (not the easiest, though) to do.

  Thanks a lot Colin and Todd for your helpful comments.  I'll try to do
  it and will tell you how it went.  Bye!
