We want to address concerns that remain post-0169. Although this proposal is primarily additive, we feel it might just squeak in under Swift 4's gate as it targets potentially harmful language issues.</div><div class=""><br class=""></div><div class="">We appreciate your feedback about the substance of the proposal. At this time, we're not looking for bikeshedding on design details. We will welcome that once the question of whether the proposal is sufficiently substantive is settled. </div><div class=""><br class=""></div><div class="">Given the extremely limited timeline and the high volume of list traffic, we're looking for specific concerns (or benefits) you see in this pitch instead of a flurry of "+1" and "-1" responses . Our primary question regards whether this is a suitable approach (it is strongly influenced by SE-0077) and flexible enough to cover at least some outstanding concerns raised in list threads over the past weeks.</div><div class=""><br class=""></div><div class="">Thank you in advance for your feedback,</div><div class=""><br class=""></div><div class="">-- Erica</div><div class=""><br class=""></div></body></html>
