> The Pickaxe book is better than anything else that I am aware of for describing Ruby idioms. I'm not sure how well it has aged.

The last version covered Ruby 1.9/2.0; the language has evolved since 2.0, so it's certainly not complete and current.

I had decided against a somewhat stronger statement; I didn't want to bash Pickaxe unnecessarily, particularly as I don't have a lot of better suggestions. I'm fairly inclined to write a book myself to address the situation, but not any time soon.
