My favorite Flex code

I've typed this exact line of code a few times, and it cracks me up each time. Just thought I'd share...it's nothing important.

var application:Application = Application.application as
Application;

That is all.

do you need the "as Application" on the end, as I didn't think you would need to caste it as an Application?

...or is it just there for the good looks? :-)

Application.application is of type Object....so it's not *necessary*, but I like to use strict typing whenever I can, letter the compiler save me from the inevitable "wtf?" I'd get when I made this kind of typo:

var someFlashVar:String = Application.application.paarmeters.foo

In reality, the code looked like this:

public function flashVar(name:String):String {
   var application:Application = Application.application as Application

   if (application.parameters == null || application.parameters[name] == null) {
      var e:Error = new Error("Flashvar not found!");
      e.name = "Environment.flashVar.notFound";
      throw(e);
   } else {
      return application.parameters[name];
   }
}

...Sorry, I should have written some code before I commented!
you are right:

trace("type is" + typeof Application.application);

traces "object", so I would be casting it to!
