Actually there&#x27;s a <i>lot</i> of support for that.  Just not official support.  But seems like if you need X to run on Y then somebody somewhere has a hack to make it happen.  Some obviously more substantial than others.<p>That, and almost <i>everything</i> has support compiling to its original target <i>and</i> JavaScript these days.<p>Nonetheless I agree with the sentiment, perhaps because I&#x27;d love to see Scala on .NET and F# on JVM in particular.  I don&#x27;t know why, of all the things that <i>have</i> happened, neither of these ever did.  Maybe too much overlap to be worth it.  I&#x27;d also have to imagine that strongly-typed languages are a bit more difficult since you have to match the underlying runtime.<p>Curious if there were any languages and targets in particular you had in mind.<p>FWIW ClojureCLR is still going strong; seems to track the JVM version within a couple weeks: <a href="https:&#x2F;&#x2F;github.com&#x2F;clojure&#x2F;clojure-clr&#x2F;commits&#x2F;master" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;clojure&#x2F;clojure-clr&#x2F;commits&#x2F;master</a>  It does have some warts, but I&#x27;ve played with it and it works fine.
