The shortest Singleton declaration!
public class Singleton {
static private var _instance:Singleton;
static public function getInstance():Singleton {
/// return _instance || ( _instance = new Singleton( new key() ) );
return _instance ||= new Singleton( new key ) ;
}
public function Singleton(singleton:key){}
}
class key{}
Thanks to John Lindquist for the fix, haha.

You can go shorter here:
return _instance || ( _instance = new Singleton( new key() ) );
to
return _instance ||= new Singleton( new key ) ;
from docs:
“||= logical OR assignment Assigns expression1 the value of expression1 || expression2.”
