&gt;Just show me the 3 things I can do in your lang that I can&#x27;t do anywhere else<p>You won&#x27;t find such a new language. Most languages in use are already known to be Turing-complete. There is no new computation that &quot;can&#x27;t [be done] anywhere else [, except in some new language]&quot;.<p>It would be highly useful to give examples of things that are easier to do in your new language though.
