Thanks, but I think this will be called every time a property is accessed. That's like `tie`'ing the underlying blessed hash in Perl, then every read write access to `$obj->{attribute}` must be handled via FETCH and STORE. This must slow down OO handling considerably. The mechanism I described above will only affect especially "enhanced" properties and only when accessed over the external interface.
