Commas are already redundant syntax to provide additional clarity over spaces in nearly all use cases. Being strict on this provides no material benefit. On the other hand, being super strict about this does have measurable, real-world impacts. I can provide examples of days of build time and breaking change back-outs because C++ lacks this very feature.</div><div class=""><br class=""></div><div class=""><b class="">Is the problem being addressed significant enough to warrant a change to Swift?<br class=""></b>Yes.</div><div class=""><br class=""></div><div class=""><b class="">Does this proposal fit well with the feel and direction of Swift?</b><br class="">Yes</div><div class=""><br class=""></div><div class=""><b class="">If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?<br class=""></b>Yes. It scales well to large team sizes as well, especially within the context of merging code together. The code that used trailing commas never has potentially build breaking merges in this same context. However, when merging C or C++ code, this is often a headache to deal with this.</div><div class=""><br class=""></div><div class=""><b class="">How much effort did you put into your review?
