Yes, exactly what I suggested in the previous email. :)
I wanted to show a general logic but this is a particular case in which
everything is more complex.
Still, I could probably overload the constructor of pyOmega to make it
really create an independent scene.
Then the inconsistency would hold maybe.
This is way beyond the simple fact that O.something doesn't need to
mention "O." in its docstring. :)
