See, that's one of the funny - if not brilliant things - with
Javascript:
a=function(a,b){alert(arguments.length);}
a('foo','bar','baz');
Guess, what arguments.length is? 3! Great, nothing's lost! How
about...
out=function(a,b){return arguments[0]+arguments[1];}('foo','bar');
alert(out);
You guessed right... out alerts as 'foobar' ...declared, anonymous,
invoked and return value assigned... all in one step.
Or, if you want to go really nasty...
x='foo';
y=function(obj){out=[];for(var p in obj)if(typeof(obj[p])=='object')
out.push(arguments.callee(obj[p]));out.push(x);return out;}
(someObject);
Declared, recursive, anoymous, invoked while using closure and return
value assigned... all in one statement!
All honours to Eric Shulman, for explaining this stuff. ;-)
