Fair enough, I usually start with the title and try to let the rest flow from there, but it's definitely the JVM that was getting me down, not clojure specifically.
I think the JVM route is smart for bootstrapping a new language since it gives you an existing ecosystem to leverage. However, at this point, I'd love to see a native Clojure.
Rich Hickey was already using a native lisp; then he wrote a couple of bridges between it and JVM/CLR before deciding running a lisp directly on the runtime VM was the way to go.
According to the article, the author moved to Janet, because it is Clojure-like without the JVM overhead.
