object.  For instance, consider code like this:
</p>

<div class="code">
<pre>
class Node {
  Object *value;
public:
  void set_value(Object *v) { value = v; }
  ...
};
</pre>
</div>

<p>
Now, consider the following Tcl code:
</p>

<div class="code">
<pre>
% Object v                 # Create an object
% Node n                   # Create a node
% n setvalue v             # Set value
% v cget -thisown
1
% 
</pre>
</div>

<p>
In this case, the object <tt>n</tt> is holding a reference to
<tt>v</tt> internally.
