I&#x27;m not bothered by &quot;hello world&quot; performance myself, and I my recent issues with Julia have been caused by rapid development meaning that when I had to put it down for a few months lots of things I had done (because I&#x27;m mortal) stopped working. I wrote this off to &quot;it&#x27;s 0.x, getoverit&quot;. I&#x27;ve never tried complex text formatting in Julia either! My concerns are more focused  on the type system (this I love) and performance for massive computation (I&#x27;ve still not managed to persuade my Hadoop admin to put julia images across our cluster, but I suppose I might win the argument one day!)
