I totally sympathize with users being confused. It's an interesting idea to move it to Array only.<br><br>The thing is, it does make sense (and wouldn't be confusing) to enumerate a dictionary or set. Moreover, the behavior is _exactly_ what it says on the tin: when you enumerate something in real life, there is no sense in which the number is related to some sort of index. Can we fix this by documentation? Like, a big blaring "don't use this when you want the index"?<br><div class="gmail_quote"><div dir="ltr">On Tue, Jan 31, 2017 at 09:35 Ole Begemann via swift-evolution <<a href="mailto:swift-evolution@swift.org">swift-evolution@swift.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On 31/01/2017 16:19, Ole Begemann via swift-evolution wrote:<br class="gmail_msg">

To clarify, the discussions I linked to don't all propose to remove or<br class="gmail_msg">
replace `enumerated()`, but they all talk about the potential confusion<br class="gmail_msg">
about what `enumerated()` does and does not do.<br class="gmail_msg">
