[ali azimi]

Hi,
   
  Thank you very much for all your supports.
   
  For the following grammar which rewrite rule is correct? 1 or 2
   
  operatorApplication
 :operatorIdentifier'('expression(','expression)*')'
 ;
   
  1->^(operatorIdentifier expression+)
   
  2->^(operatorIdentifier expression)+
   
  Best wishes,
   
  Al
