   Dogelog Player is a Prolog system mainly written   
   in Prolog itself. A library(pio) for Pure I/O is   
   not part of this Prolog systems. Herein we report   
   a successful experiment of implementing such a   
   library. The library has a Web 2.0 realization   
   since the streams can even originate from URLs.   
      
   Instead of going with memory mapping or attributed   
   variables, our main idea is to use ‘C’/3 to   
   detect Haskell lazy and realize it with change_arg/3.   
   The grammar backtracking is potentially unlimited.   
   There is a separation of concern into a get_lazy/3   
   and the unit need not be codes.
