OK, now it really works like I wanted it to work :

        index_html  ==> renders as HTML
        <dtml-with> ==> access to the object's methods and properties
        <dtml-var obj> ==> same as index_html
For those who might be interested, I've just defined a __str__ method
which renders my object as HTML, then defined an index_html method
which just returns str(self), and no need for a __call__ method.

No, I wanted to keep it simple to use
