CGAL users discussion list

Hi all, 

    I am just getting started with knowing how to use CGAL, and I'm 
particularly puzzled about something. 
    
    In the class Point_2 , or whichever class that defines the 
location/position of a geometric primitive, is it possible to change the 
position of the class? 

    Like for instance, 

    Point_2 myLocation(5,0);
    myLocation.x = 10; 

    Can i do something like this in CGAL? Thanks if anyone can provide me 
with an answer on this. 

regards
Calvin
