Hi Yonatan,

In general: You can assign a reference to any class above the inheritance
tree and to any interface any of these classes is implementing without a
cast.

A reference stored at any of these more general types can be casted "back"
to a more specialized type down to the original.
Here cast is a must.

At any point the reference is the original object (will show if it is asked
for).

By casting you cannot "change" an object like it works in some respect in
C/C++.
Greetings
Michael.
