this is great
but i have 2 problems so far:

// prototype relationship test
Foo.prototype.bar=function(){
  print(this.f);
}
function Foo(f){
  this.f=f;
}
foo=new Foo(10);

print('serialized foo: ' +  serialize(foo, 'foo') + '\n');
eval(serialize(foo, 'foo2'));
foo2.bar();

print(foo.__proto__.bar);
// should print function
print(foo2.__proto__.bar);

// graph test
print("-----------------------------------------");
graph={x:foo, y:foo};
graph.x.f=12;
graph.y.bar();
print('serialized graph: ' +  serialize(graph, 'graph') + '\n');
eval(serialize(graph, 'graph2'));
graph2.x.f=77;
// should print 77
graph2.y.bar();
