Hi,

Is there a method to access this reference of the container class
from an inner class. i.e.
class A {
class B {
   methodM() {
      callAnotherM(A::this or A.this);
   }
}
}

Thanks

The outer class is referenced via the property outer. However, if the inner 
class is static, then it has no such property and is not tied to a specific 
instance of the outer class. In such a case, it can access the private members 
of an instance of the outer class, but it's not tied to an particular instance. 
Non-static inner classes (like yours above), however, _are_ tied to a
particular 
instance of the outer class, and they have the outer property which is the this 
of the outer class.

Just to add a note, you have to access the property via "this":

this.outer

That, I did not know. But I've never actually used an inner class in D thus
far. 
I just read what TDPL says on it, and obviously I missed that point. Thanks.

I have noticed that, is that a bug?  I always thought it strange, since  
outer is a keyword, that you need to do this.outer.

It's not a keyword. It's a property of non-static inner classes. It's like 
length on an array. It's always there, but it's not a keyword.

You're right, it isn't.  My text editor highlights it like it is, so I  
just assumed...

My question still stands though, why the requirement to use this.outer  
instead of just outer?
