Here's some code:
---------------
public class Obj : Object {
public string foo;
}
public void main() {
var o = new Obj();
var o1 = new Obj();
var o2 = new Obj();
stdout.printf("&o %p\n", &o);
stdout.printf("&o1 %p\n", &o1);
stdout.printf("&o2 %p\n", &o2);
//YAY!!!
string s = "%p".printf(&o2);
stdout.printf("o2 with & op: %s\n", s);
//TEST WITHOUT THE & OPERATOR - The output differs:
s = "%p".printf( o2 );
stdout.printf("o2 without & op: %s\n", s);
s = "%p".printf( o );
stdout.printf("o without & op: %s\n", s);
}
---------------
On my system I get this output:
&o 0x7fffc55de458
&o1 0x7fffc55de460
&o2 0x7fffc55de468
o2 with & op: 0x7fffc55de468
o2 without & op: 0x153d090
o without & op: 0x153d030
For interest's sake, why is the output from &o different to o? Which
would you use as a unique key?
