In my opinion syntactical sugar is best used to enhance readability rather than aid beginners. I promise that you'll learn to remember the commas.

Perhaps it is obscure to you, but a lot of people use and like that syntactical sugar. It makes certain things cleaner, especially emulating named parameter calls:

create_box { width = 2, height = 3 }

as opposed to

create_box({width = 2 height = 3})
