I think I'm with Eric F. on this.  Given some long chain of calls: X, A, 
B, C D, ... Y, can that be refactored so that X calls Y directly?

   void methodX()  {
     A();
   }

to

   void methodX() {
     AResult result = A();
     X( result, otherData );
   }

I'm thinking that if your methods have to pass data through a long chain 
of calls, then the code is badly structured period.  You might as well 
use the opportunity to refactor rather than trying to invent a "wormhole."

I can think of at least one way to implement a wormhole.  I'm just not 
going to go there because it's a terrible idea.
