Sorry about this, but there has already been much discussion of this
issue and the agreement was that array functions that returns 0d arrays
should return python scalars.  I agree that this can occasionally be
confusing, but I think that our conclusion when we last discussed this
was sound (look at the archives if you're feeling brave).
