After discovering Haskell (lazily-evaluated functional) and Lisp (actually, Clojure), I&#x27;d have to say them. For anything close to the metal where pauses for garbage collects don&#x27;t matter, Go. And of course HTML. (Tho I realize some people out there won&#x27;t count as a PL non-Turing Complete languages like HTML and Groovy as used in virtually every Gradle build script out there.)
