Accessing anonymous reference inside with block

[Andrej Mitrovic]

Here's an example from DFL where I'm using an anonymous Scintilla
object which is a subclass of a text editing widget in DFL (just
another window subclass), but behind the scenes it actually loads the
Scintilla DLL and behaves like a normal DFL text editing widget:

What really happens in DFL is that assiging the "parent" variable of a
window class object (lets call it client) to another window class
object (call it host) means that the host now holds a reference to the
client. So the client will not be destroyed unless any of it's destroy
methods are explicitly called, or if the host window is destroyed then
the client window is destroyed as well (this is how DFL works).

I think that's how it works. If I'm wrong someone can correct me, though. :)
