I actually wrote a Julia version at the time, but it was difficult to accurately benchmark because the total runtime was significantly affected by a long (~5 seconds) delay at startup.

Recently, however, I came across https://www.reddit.com/r/Julia/comments/4c09m1/, which suggests running with `--precompiled=yes` to reduce startup time. I have now run the Julia version with that command-line option, and the runtime is impressive - comparable to C#/Go/V8.

Most Julia users run code more often in an interactive REPL session rather than as a script to do a single thing. The precompiled code loading is now on by default on Windows in Julia 0.5 since the backtrace issue was fixed, but there's still a 0.3-0.5 second delay on startup at the moment.

Very cool
