Ruby-style metaprogramming in JavaScript (plus a port of RSpec)

Programming in Ruby makes me happy. It’s a lovable language, with a pleasantly quirky syntax and lots of expressive power.

Programming in JavaScript, on the other hand, frustrates me to no end. JavaScript could be a reasonable language, but it has all sorts of ugly corner cases, and it forces me to roll everything from scratch.

I’ve been trying to make JavaScript a bit more like Ruby. In particular, I want to support Ruby-style metaprogramming in JavaScript. This would make it possible to port over many advanced Ruby libraries.

You can check out the interactive specification, or look at some examples below. If the specification gives you any errors, please post them in the comment thread, and let me know what browser you’re running!
