If you rewrite your app you end up with something better, in any language. It&#x27;s an uncontrolled experiment, and so the headline is very likely misleading - this isn&#x27;t about Python and Lua. And many of us have been majorly inconvenienced when a manager read a similar headline and declared that we would rewrite our app in language y, regardless of whether that language is appropriate to our circumstances.<p>Something like <a href="http:&#x2F;&#x2F;roscidus.com&#x2F;blog&#x2F;blog&#x2F;2013&#x2F;06&#x2F;09&#x2F;choosing-a-python-replacement-for-0install&#x2F;" rel="nofollow">http:&#x2F;&#x2F;roscidus.com&#x2F;blog&#x2F;blog&#x2F;2013&#x2F;06&#x2F;09&#x2F;choosing-a-python-r...</a> where the author actually considers multiple candidates and performs a controlled comparison would be far more valuable.
