Ruby was one of the languages I "cut my teeth" with to some extent, and I've always loved it's syntax and guiding philosophies, but was pulled away to PHP for my job, and ended up using other things for side projects.

So a project that compiles to native code but uses Ruby-like syntax is very much "what I would build if I committed to building a language". But I've kept pushing off learning it on the notion that I could always justify learning other things that were "version 1" and "production ready (whatever that means)".

I'm thinking now is the time to jump in and try this out finally.

Any real world users care to explain some domains that either are or are not well suited for this at the moment? Any "gotchas" with writing C-bindings, should I need to? Or is the library ecosystem fairly strong?
