> Same way an actual, legitimate newbie to Rust is going to have much more difficulty processing why :: is the namespace delimiter or why you need curly braces to deliniate scope than how having the option to declare your function const would. I disagree. :: and curly braces are just a shallow bit of syntax: you see it, learn it and it doesn't interact with anything. It is the easy part of learning the language. For example Go has curly braces too, and it is one of the fastest languages to get started with. Maybe const functions are not visible immediately, but then as a beginner you would start looking at some documentation, and you'll see const there in API documentation and not understand it, so that makes the language look like it has these opaque features you do not understand. I'm not saying const functions are not worth the cost, I'm just saying that they do have a cost and add complexity in a way :: and curly braces do not.
