Just to clarify, what happens at Christmas is the first proper <i>language release</i> (as specified by the test suite) that will be accompanied by a conforming compiler release, ie the main focus is still semantics, not &#x27;production readiness&#x27;.<p>That said, Rakudo of today is more usable than Rakudo of days gone by, though there are still issues (my personal pet peeve: parsing speed; <i>hopefully</i>, automatic precompilation will land in the not-too-distant future, which, would mitigate the problem).
