Thank you, Matt! I just miss finalization section in the ECL manual.
I am sorry: the references had disappeared almost entirely due to an upgrade of the manual to support Docbook 5.0. If you go back to http://ecls.sourceforge.net/new-manual/ you will find again the manual pages for ext:get-finalizer and ext:set-finalizer.
One word of warning, though: finalization has a penalty which is not to be ignored. A more performant option might be to have a custom "new" method that uses the garbage collector as memory manager. I believe the Boehm-Weiser library has examples on how to combine C++ and its collector.
