I think a good idea would be to look through Ruby Enumerable (which is most excellent!) and see how things correspond to P6, or where they are missing. Like in this case you can do:<p><pre><code>    [2,3,5,&quot;hello&quot;,42,3.14].any ~~ $x
</code></pre>
But that&#x27;s not really the same, since it converts the entire array to a junction and then does the match. Really this is a lot closer:<p><pre><code>    [2,3,5,&quot;hello&quot;,42,3.14].first($x):p
</code></pre>
Which returns the first match (as a pair (hence the :p adverb) so it won&#x27;t be false even if it is a false value)... but it isn&#x27;t right either because it gets mad at comparing numbers and strings (I&#x27;m asking about this in #perl6 now on irc).<p>Ultimately: it would be trivial to port ALL Enumerable methods to Perl 6 List (or some role to cover all iterables or such), and do it in a library even if it wasn&#x27;t in the core standard lib.<p>I&#x27;m always fascinated by how much of Ruby (and lots of other languages) are more about their Standard Lib than about their language. In the Ruby world, lots of people end up with ActiveSupport, which sprinkles in all sorts of cool stuff into the standard lib -- and I&#x27;ve ever seen a native &#x27;for&#x27; loop rather than a .each in pragmatic Ruby.
