in reply to object swizzling?

Since what you call objects are really references, if you just re-bless $x into SomeOtherClass and assign it to $z, then both variables point to the same object, and methods that modify it will affect both variables.

Of course if you want a proxy that just "intercepts" some method calls and forwards most of the rest, you could just inherit from the class you're trying to proxy.

    I guess that will work. I just have to make sure that my proxy is of the same underlying type (HASH, ARRAY, SCALAR) as the real object.

    In the lazy-load case I want to ensure that the real object is loaded before forwarding, so it's not that simple.

      You can call the super class's constructor first: 
      package 'Bar';
use base 'Foo';
sub new {
  my $class = shift;
  my $parent_class_object = SUPER->new();
  ...
}

      And then store it, or use it, or rebless it, or whatever.
