// everyone's new favorite closure pattern:
(function(window,document,undefined){ ... })(this,this.document);

// when minified:
(function(w,d,u){ ... })(this,this.document);

// which means all uses of window/document/undefined inside the closure 
// will be single-lettered, so big gains in minification.

// it also will speed up scope chain traversal a tiny tiny little bit.

def tree(): return defaultdict(tree)

That's it!
