If I use something like 

ROUTINE[ANY, TUPLE]

as explained here:

http://www.jot.fm/issues/issue_2004_04/article7/

I get this compiler warning:

****** Warning: The base type is no longer used. Class ROUTINE
now has only one formal argument. Just remove this unused type
mark.

Line 9 column 21 in IUP_WIDGET
(/home/german/Instalados/tests/liberty/iup_test/auxiliary/iup_widget.e):
   cb_action: ROUTINE[ANY, TUPLE]
                      ^          

As far as I understand, this first argument represent the object which
to routine belongs. But according with the warning, this argument is not
used anymore. So, how know Eiffel where should be executed that routine?
This seems to be the problem. Because I'm doing this using as reference
the article I cited above.
