Try using
Automagically(Finish_AllMyTasks) ie move the underscore to give cleaner distinction between the method (ie
Finish) and what it is to be applied to (ie
AllMyTasks).
I tried it here and it mostly works, except that for some reason it refuses to make coffee. I think this could be because the coffee maker's monthly firmware update is late, something to do with still trying to fix the overflow error caused by the previous update.
