Hi Stéphane, Thanks for your feedback. I agree that the usefulness of these results is limited. However, if we (Object Guild) want to make a case for energy efficiency, it can help if the language itself can be shown to be efficient as well.
For now, I think the efficiency will need to come from a good object design. Kind regards, Jonathan van Alteren Founding Member | Object Guild B.V.
