You misunderstand. The idea is this:

void foo( ) {
   Object p;
   if ( m ) {
     p = new Object( );
     p.DoSomethingThatNeedsToBeDoneNow( );
   }
   // 20 lines of code here
   if ( m ) {
     p.doSomethingWeird( dataFromAbove );
   }
}

I'm not sure the compiler actually does this, but it would be fairly
trivial to inline that delegate.
