Clearly they added a bunch of new stuff that the JVM can&#x27;t understand.<p>So it is either &quot;Scala like LISP&quot;<p>or<p>It is a superset of the Scala language. Meaning all existing stuff will work with it, but if you use new secret keywords it will work &quot;better&quot;.<p>Which seems not quite ideal, because that means most Scala libraries will not be &quot;tuned&quot;, and you will need all new libraries.. just like ScalaJS made you need entirely new Scala libraries that did not use reflection.<p>Worried the Scala ecosystem is turning into a nightmare ;)
