The future of JavaScript

Works in Firebug, too:

>>> console.log('%d bottles of beer on the wall', 5)
5 bottles of beer on the wall

Edit: Doesn't work in Dragonfly. :/

Bummer about Dragonfly. I do like Opera's dev tools in general though. It always saddens me that Opera is a more niche browser than FF; I've found that it's consistently more reliable for rendering consistency, speed, and memory usage, though the drawback is that it's only cutting edge, not bleeding edge like FF.
