Just to make your code a little more clear, try using aliases 
when defining delegate parameters. Like this:

alias Action = void delegate();

Then in your code you use the alias, like this:

class Bar()
{
     private Action _action;

     void setAction(Action d)
     {
         this._action = d;
     }
}

IMHO it makes everything more readable and you only have one 
definition of the delegate signature.
