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?
