   "Short" in my dictionary is. One. Single. Screen. No more. No less (pun   
   intended).   
      
   And this one is one single screen. Even with the dependencies.

   Typical use:   
      
   variable a   
   variable b   
      
   : divide   
      local a   
      local b   
      
      b ! a ! a @ b @ / ;   
      
   Does recursion, the whole enchilada. One line.   
   Thanks to Fred Behringer - and Albert, who condensed it to a single   
   single line definition. Praise is where praise is due.
