As they pointed out, they conflated optional trailing commas and optional commas in general in the options, which means they can't read too much into those. I don't think anyone wants the latter, but I think the former would be really nice

kevinmost: Trailing commas look ugly and untidy to me. Even in JavaScript I use a lint setting that throws error on a trailing comma. If you need to move arguments around, I recommend ctrl+shift+alt+→ which takes care of the comma for you.

I use IdeaVim and vim controls to reorder my params, so I can't rely on the IDE to move the comma. I'd also rather just have less noise in my diffs by being able to move lines without touching others, regardless of their position

[poohbar]

well then your tooling is lacking ... the extra line in diff is less distracting to me than dangling commas

[kevinmost]

I don't think I should have to rely on the tooling to reorder lines of code. I don't see trailing commas as a distraction at all. Would be interesting to see them in a future community survey if another one gets run, without the "all commas are optional" part, to see how it's received

All commas are optional is not implementable. It would be a breaking change to the language.

listOf(1
+2) == listOf(3) // now

listOf(1
+2) == listOf(1, 2) // after

Optional trailing commas FTW.

@mg6maciej A really bad idea for code compatibility and that'd make multiline expression list elements not possible or not readable
