Suppose I "connect" a function to a class using callbacks:

Class.WhenBLAH = THISBACK(fn);

Now, I need to temporarily disable this callback, altough I've not found a suitable "null" value for the Callback type. The following obviously do not work so far:

Class.WhenBLAH=THISBACK(NULL);
Class.WhenBLAH=NULL;

Both are incompatible with Upp::Callback.

How I can do this?

You can use Class.WhenBLAH = Callback() to denote a "null" callback, as in no action.
