A good read for anyone just starting out with some of the more intricate parts of Ruby.
I often think Ruby is unsurpassed for writing readable, English-like DSLs - perhaps because of the combination of the convenient lassitude of Ruby's syntax (not requiring brackets - in many cases - or semi-colons) and the dangerous power of its metaprogramming abilities. The only other language that perhaps comes close and immediately springs to mind, before I've had my first coffee of the day, is (appropriately) CoffeeScript. Any other takers?
