   The problem with f and f1 is that you should use 'x..' instead of '[x..]':   
       f(x:PI):Stream INT==(return expand(x..))   
       f1(x:PI):Stream INT==(expand(x..))   
      
   And g and g1 and g2 work in FriCAS (a fork of Axiom).   
      
   Dude, you should post this kind of problems in one of the axiom   
   mailing lists instead of this generic list, you can post in:   
      
   The AXIOM mailing list:   
       https://lists.nongnu.org/mailman/listinfo/axiom-developer   
      
   Or, the FriCAS mailing list:   
       https://groups.google.com/forum/?hl=en#!forum/fricas-devel   
      
   Or, the OpenAxiom mailing list:   
       https://sourceforge.net/p/open-axiom/mailman/open-axiom-devel/
