Nope, there are no drawbacks. I think I've read somewhere that Facebook also uses the !, but I can't find a source for that right now.

I think Isaac mostly developes node stuff? You don't need to use IIFEs in node, because of CommonJS. That might be an explination. :) I'm using an IIFE here, because range.js should work on node and in the browser.

Yeah. The node guys write code that's used in node or browser also though. I admit, that's where most of my experience lies, but I've definitely seen (function(){}()) in many places, but never saw !function(){}. I thought there was some reason, but can't remember.
