Looks like just a week before I sent this Tango got weak pointers.  So 
now you can do a similar thing in Tango too.
     http://www.dsource.org/projects/tango/forums/topic/341

BTW tango's names for the subscribe/unsubscribe functions are slightly 
better-named than Phobos'!
     rt_attachDisposeEvent and rt_detachDisposeEvent
  vs
     notifyRegister and notifyUnRegister

They're not documented in Phobos, so it's not too late to pick some 
better names (or provide some better aliases anyway)!
