   Hi all,   
      
   for specifying the syntax of operator expressions   
   with multiple levels of precedences,   
   there are essentially two approaches:   
   (i) by precedence and associativity declarations, and   
   (ii) by a hierarchy of non-terminals.   
   Both approaches have been known and in use for decades.   
      
   My question is:   
   Are there trends in the public opinion   
   in favor of one of them over the other?   
   Or are they equally respected approaches?   
      
   Best regards,   
   Andreas
