   Yeah, that was intentionally bold ;-).   
      
   It looks like you and I have a different definition of a "global state".   
   This discussion is about singletons, and (no surprise there) it had led to   
   global variables. And those make me shudder, and you, too, I think ;-).   
      
   How about this: yes, there is global state, however, a given point in code   
   is using only a part of it. My argument is: we should pass that part into   
   said code; when we have "global" variables, code invariantly gets lazy and   
   uses part of the state from parameters, and a part from globals. That   
   results in messier than necessary situations.
