    <p>To keep pages seperate, we run them in different namespaces, in
    order to make sure local variables are really local:</p>
    <p>
    </p>

This is ok, because 'greeting' disappears when the 'request' namespace
is cleaned up after each page:
    <pre>
namespace <span class="keyword">eval</span> request {
    set greeting <span class="string">&quot;Hello, World&quot;</span>
    puts -nonewline $greeting
}
namespace delete request
</pre>

The following code will fail, even if called after the first page
above, because 'greeting' has gone away.
<pre>
namespace <span class="keyword">eval</span> request {
    puts -nonewline $greeting
}
namespace delete request
</pre>
