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.
