I haven’t done that for years.
And it was Java code anyway. 


Circle roma = new Circle();
Circle lasciate =

   new Circle("Paradiso",
              null);

roma.copa="Pizza";

Circle ogne =
 new Circlo("Purgatorio",

            lasciate);
roma.capo=lasciate;

Circle speranza =
 new Circle("Inferno", ogne);

Dante alighieri = new Dante();

speranza.tutti(alighieri);

roma.reformatzi();

ogne.tutti(alighieri);
