  Oh right, I should have thought of this.

  No, as you can guess that does not really serve a useful purpose.

  I'm sure I could, but since the actual data is hidden from the user
anyway there is little advantage in doing that.  In the current
implementation I just have a function of two arguments that returns the
content of the table (internodes), and I think that's a more sensible
interface.
