I totally agree that a renaming is required and I agree with most of the proposal for the exception of the slicing subscripts. If the goal of the proposal was to make those APIs easily discoverable, then those subscripts go completely against that:</div><div><br class=""></div><div><ul class="MailOutline"><li class="">You need to know that the subscripts exist and if you are looking for a method, you will never find them.</li><li class="">They use a new type which is never used anywhere else.</li></ul><div class=""><br class=""></div><div class="">On a more general note, creating new types in the Standard Library only to serve as arguments for those fairly rarely used subscripts sounds very heavy-weight.</div><div class=""><br class=""></div><div class="">I vote for keeping functions for those operations.</div></div><br class=""><blockquote type="cite" class=""><div class=""><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>* Is the problem being addressed significant enough to warrant a change to Swift?<br class=""></div></div></blockquote><div><br class=""></div><div>Yes.</div><br class=""><blockquote type="cite" class=""><div class=""><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>* Does this proposal fit well with the feel and direction of Swift?<br class=""></div></div></blockquote><div><br class=""></div><div>Yes, except for the subscripts, which look fairly alien to me.</div><br class=""><blockquote type="cite" class=""><div class=""><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>* If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those?<br class=""></div></div></blockquote><div><br class=""></div><div>No.</div><br class=""><blockquote type="cite" class=""><div class=""><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>* How much effort did you put into your review?
