[Laszlo-dev] Someone should see if `var global = this` at top level works in swf9

[Donald Anderson]

Nope - didn't work for me like that, got this error:

    The this keyword can not be used in static methods. It can only be  
used in instance methods, function closures, and global code, in  
line:   public var globalthis = this;}

The line compiles into its own file globalthis.as:

   package {
   public var globalthis = this;}

You can use 'this' as long as it isn't in a var initializer however.
You can use this to indirectly set the global variable if you want.
For example, this works:

   var globalthis;
   function setThis(thisvar) {
     globalthis = thisvar;
   }
   setThis(this);

   function stuff(foo) {
   }
   stuff(globalthis); // I can use the globalthis now.
