> In the case of non-trailing commas it's exactly the same - something you need to remember to add. And remember to (re)move when you move arguments around, that's also buggy cognitive overhead. That’s exactly why I’m advocating that trailing commas should be optional ;) > Expressions don't require zero spaces, use (), this was just an illustration that there is no need for a comma. You’re example specifically stated using zero spaces for expressions though. So that’s what I’m replying to. I have no issues with parentheses being used to denote an expression. In fact that largely mirrors how my own language works.
