This isn't getting us anywhere. We disagree. I value the opinion of that lot given their many decades of experience. I used to have your opinion, based on textbooks. They've made a good point, one I can see has considered thought behind it.
I do have compiler development experience, but alas as you say this is not getting us anywhere.
