Hi,

The list is not aplaceholder ,just a set of values and for returning a set of values , an array or an arrayref is better than a list and any fuction returns a set of variable values which are not constants and hence an array is better and mostly used than list

     sub list {

           return(1,2);
 
     }

is not often used

     sub arrays {
    
          @A = (1,2);
          return (\@A);

     }

is something often to use in sub
