In that case, I obviously wouldn't have any problem with that approach
(it sound even better :)). Is there any place where I could get a bit
more documentation about how this "SLOT operator" way would work? For
example, how would work for rebuilding x11 drivers after updating xorg
or rebuilding gobject-introspection after major glib update... 

Thanks a lot for the info :)
