Thanks for discussing this! I'm an intermediate programmer learning iOS Swift programming right now and was a bit confused when I saw the SwiftUI demos. Finally someone who explains what's happening!

Wikipedia about syntactic sugar:
> syntactic sugar is syntax within a programming language that is designed to make things easier to read or to express. It makes the language "sweeter" for human use: things can be expressed more clearly, more concisely

You implicitly say it in the video, but:
The lack of the `return` keyword here is nice.. for seasoned developers. Removing explicit keywords from the codebase makes it harder to take junior developers onboard.
In relation to the definition above, it makes things "easier to express", and "expressed more concisely", but not "easier ro read" nor "expressed more clearly".
