All,

How can I access a reference to an enclosing class in D? ... something similar
to the following Java code:

class A {
  class B {
    A ref;
    B() { ref = A.this; }
  }
}

You can use the *outer* keyword to access the class wrapping a nested class.

Like:

class Outer
{
     class Inner
     {
	Outer foo()
	{
	    return this.outer;
	}
     }

     void bar()
     {
	Inner i = new Inner;
	assert(this == i.foo());
     }
}
