I just committed a version where this is implemented (trunk rev. 78785). You
can play with it and see if it solves your problem. I'm pretty confident it
will work, but I need to make more tests and update the doc (but it's
getting late).

For non-eUML front-ends, boost::any is now an acceptable event, for eUML I
added an event named "kleene" behaving like a boost::any. With both, the
original event is saved in the boost::any, which allows you some more
entertaining guards or actions ;-)
