Sure, but it also means that you can duplicate an object just by duplicating
its contents. Which also means you can spoof any object just be replacing the
contents with a value that happens to be the ID of another.
That's why I decided against caching the key in the object.
Of course, nothing prevents you from doing this manually yourself. For
example, you could set up a BUILD that includes:
$$self = ident $self;
and thereafter use $someattr_of{$$self} as you wish.
