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.
