I don&#x27;t think it&#x27;s fair to characterize Rakudo Perl 6 as incomplete, at least on the MoarVM backend.  It is very nearly complete, with the bulk of the semantics fixed in years past.  It is currently passing 122627 tests[1].  If you write code today, it will probably not break by December.<p>I guess it still counts as unstable software, but I used Gmail beta for half a decade and that turned out fine.  At this point, its a matter of nomenclature, because I&#x27;ve certainly used buggier &quot;final release&quot; software.<p>[1]: <a href="https:&#x2F;&#x2F;github.com&#x2F;coke&#x2F;perl6-roast-data&#x2F;commit&#x2F;2aeeb87edc" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;coke&#x2F;perl6-roast-data&#x2F;commit&#x2F;2aeeb87edc</a>
