<div class="">How about the goal of it being a delightful language to program in. I think that is getting lost in proposals like these. Optimizing for some mythical new user, who really isn’t present on this list to give an opinion seems like a false argument to make,
and your technical sophistication makes you a less qualified than most to say what is and what isn’t confusing to new users because you haven’t been one in a long time.</div>

<div class="">-1 Leve it in. It is perfectly simple as is. Not confusing at all. There are far more confusing aspects to the language than this.</div>
