I have now split that example in a simpler expository example membrane at <http://wiki.ecmascript.org/doku.php?id=strawman:proxies#a_simple_membrane> that does not preserve identity, but that should be read first, and an elaboration of our identity preserving membrane, still at <http://wiki.ecmascript.org/doku.php?id=strawman:proxies#an_identity-preserving_membrane> with a bug fixed and with both wrapping and unwrapping logic that makes it into a practical membrane. -- Cheers, --MarkM _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
