   I am sorry, I can't agree with this. On paper, one writes  y(x)   
   not   
      
       y x   
      
   Since y x means multiplication, on paper also.   
      
   So  Axiom/FriCAS notation is very confusing and makes reading   
   it hard and ambiguous. But since one can write y(x) also,   
   so it is not a big deal.
