class PlayerLoginEvent : Event!(PlayerLoginEvent) {
        int x;
}

src\Event\Event.d(41): Error: cannot implicitly convert 
expression (handler_) of type shared(HandlerList) to 
ghrum.event.HandlerList.HandlerList!(PlayerLoginEvent).HandlerList
src\Event\Event.d(51): Error: cannot implicitly convert 
expression (handler_) of type shared(HandlerList) to 
ghrum.event.HandlerList.HandlerList!(PlayerLoginEvent).HandlerList


The last function is:

        final static public HandlerList!T getHandler() {
                return handler_;
        }

I just fixed by replacing shared with __gshared. Another issue 
that i have is that if i have.

public class Event(T) {
        static public HandlerList!T getHandler() {
                if( handler_ is null ) {
                        handler_ = new HandlerList!T();
                }
                return handler_;
        }
}

public class MyPlayerEvent : Event!MyPlayerEvent {
}

MyPlayerEvent.getHandler(); -> Error: need 'this' for getHandler 
type HandlerList().

Thanks in advance!
