It's been serving you pretty well, you can write all kinds of neat things in your code that would otherwise have been much uglier like:

And you're generally very happy with your life. Then you go and do something like use Array#uniq. You'd expect it to work, because naturally it would be implemented using "==".

That's what. And *now* your precious Array#uniq will work.

Enjoy!
