Subject: [Ruby/SDL] how do I inherit from SDL::CD ?

I gurus and nubys,
I was playing a little with Ruby/SDL and tryied to subclass SDL::CD.
After little problems I discovered that SDL::CD.new was not a
documented feature and that the only way to get an instance of SDL::CD
was via SDL::CD.open.

the strange  thing is that the object I get from CD.new seems a valid
CD object:

>>> a=SDL::CD.new
=> #<SDL::CD:0x40218e20>
>>> b=SDL::CD.open 0
=> #<SDL::CD:0x402146f4>
>>> a.methods==b.methods
=> true
>>> b.status
=> 1
>>> a.status
TypeError: wrong argument type SDL::CD (expected Data)


So, #new is bad.. but how could I inherit from a cd object if I can't
use #new? 
And why #new act this way ?
