  1. Very bikeshed. The only meaningful arguments I’ve ever heard in support of the practice are “it makes templating and transformation by regex easier.” The compiler certainly doesn’t care in operational cases.

    “Cleaner” diffs are an opinion on the order of “clean code,” albeit with marginally superior provenance. If you’ve seen a few diffs, you know what you’re looking at from experience. If you haven’t, the reduction is fairly obvious.

    There’s a stronger argument to be made here for left-sided dots and commas. All the benefits if you care, no fashion characters.
