How does this compare to OpalRb?

[ylluminarious]

Hi @TIMahoney,

Just saw this and thought it was interesting. I'm curious, though, as to how it compares to OpalRb, another project which uses Ruby in place of JavaScript.

I assume that this follows a similar principle as Opal, in that it transpiles Ruby to JavaScript. I'm also curious if this project works outside of WebKit, and if it's active / working anymore.
