in thread strange comma

Without the extra comma, adding something to the list requires going back to the "clean => ...." line and adding a comma, and then adding the new thing on the next line.

In addition to that, it also means that the diff between revisions in your VCS (which you of course use, whichever one you use) ends up having that extra -/+ pair of lines just to add the comma, which makes it that much slower to scan visually.

    ends up having that extra -/+ pair of lines just to add the comma

    That leads one of my two reasons for using it: It's easier to add a comma at the end of the line you are typing than to have to modify two lines (instead of one) when adding a new item to the list.

    (The second reason is that I think it looks better with the comma.)
