<div name="messageBodySection" style="font-size: 14px; font-family: -apple-system, BlinkMacSystemFont, sans-serif;">`integers.all { $0.isEven }` reads like an alias of `filter` to me. The meaning is ambiguous because the missing argument label can be filled in in different ways -- some will read this as "all are even", and others will read it as "all that are even".
<div><br /></div>
<div>I think that ambiguity should be avoided. Something along the lines of `integers.allMatch { $0.isEven }` does just that and reads quite nicely in my opinion. I also like `integers.containsOnly { $0.isEven }` a lot since it pairs nicely with the existing `contains` method.</div>

</div>
<div class=""><br class="" /></div>
<div class="">Without the argument label it’s not as clear what it does, but other functions have a similar problems when used without argument labels. For example, </div>
<div class=""><br class="" /></div>
<div class="">xs.prefix { $0 > 5 }</div>
<div class="">xs.drop { $0 > 5 }</div>
<div class="">xs.index { $0 > 5 }</div>
<div class=""><br class="" /></div>
<div class="">It uses terminology well, if `all` is accepted as a term of art. It is at least a common term in other languages for this functionality. </div>
<div class=""><br class="" /></div>
<div class="">However, one area where it doesn’t hold as well (ignoring any term of art argument) is that Boolean methods [...] should read as assertions […] when the use is nonmutating. Here I kind of like the `are` prefix, similar to how `empty` has an `is` prefix (isEmpty). In this case I would also like to see the labels change for a more fluent usage: `areAll(equalTo:)` and `areAll(matching:)`.</div>
