Summary0000507: An efun " this_closure() ", that returns in a closure a pointer to the closure.
DescriptionIt would be nice to have an efun this_closure(), that returns in a closure a pointer to the closure.

add_controller("notify_move",
               function void ()
               {
                  write("Write this only for exact one move.");
                  delete_controller("notify_move",this_closure());
               }
);

You could code something like this:

closure cl;

add_controller("notify_move",
               cl=function void ()
                  {
                     write("Write this only for exact one move.");
                     delete_controller("notify_move",cl);
                  }
);

But that has the disadvantage of a recursive data structure.
The memory might not be freed, if the closure is no longer used,
because the reference count can't be nulled because of the self reference.
