Well, it's ugly but it *is* doable within the rules, and I already have an appropriate code point to make that work out. (Nice that the first argument of each trap is the proxy target.) Regarding .hasBeenRevoked, yes, I get that too. The revoke function from Proxy.revocable() handles only the proxy itself, no administration of metadata around that. Oh, well, it was worth a shot. -- "The first step in confirming there is a bug in someone else's work is confirming there are no bugs in your own." -- Alexander J. Vincent, June 30, 2001
