What was wrong with the UUID proposal? It sound like you abandoned that idea. I interpret it to mean create a scalar ref whose object is a unique number. Then, the dereferenced value, not the volatile address, becomes the object key. The UUID proposal would have much less overhead than having a CLONE method repair all the dangling links in each hash.

    I didn't spot anything wrong with it; I just didn't address that part of the problem.

    After Compline,

      I thought that if we got away from using the refaddr, we would solve the problem. Won't the following methodology work? Here is my attempt to create an alternate ID. I don't want to post the whole program inline; here are the changes.
      11c11,15 < *ID = \&Scalar::Util::refaddr; --- > sub ID ($) { > my ($self) = @_; > > return ref($self) ? $$self : ''; > } 28c32 < *{ $caller . '::ident' } = \&Scalar::Util::refaddr; --- > *{ $caller . '::ident' } = \&Class::Std::ID; 360a365,366 > my $count = 0; > 370a377 > $$new_obj = $count++; 512c519,523 < *ID = \&Scalar::Util::refaddr; --- > sub ID ($) { > my ($self) = @_; > > return ref($self) ? $$self : ''; > } 519a531 > $$new_obj = $count++;
      We won't care if the address of the anonymous hash changes; that is not the key. We have an alternate key that stays in tact. This is my first stab at it. When I made tried this on my Mac, I barfed on the coercions test.
