> 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.

I do not know what is energy efficient nor how it is measurable.
Now our objectives is that pharo does not burn the batteries when doing nothing and we start to have that with the headless and idle vm.

this would presume that message passing is faster than branching.
And I remember that we had argument with hardware people about our reengineering pattern
on condition to polymorphism
