Julia support

[eo1989]

I see from our documentation that Ruby has a lot of attention, & I know that a good bit of Julia's syntax is somewhat largely based on Ruby (w/ a few other language's as well), it leads me to wonder if many of those plugin features could be readily applied to Julia, or if there would need to be some minor adjustments made?

Sorry, forgot to add an enhancement flair to the issue.

Heh, ruby gets the most love because I use it at work. If you want to expand on the built-in julia support I'd happily take a PR. It should be pretty straightforward to use the same functions for both. I just don't want to add features for a language that I don't know, since I couldn't tell how idiomatic/useful they actually are.
