The point being that if a membrane can't abort such accesses, then collaborators on both sides of the membrane could circumvent the membrane by communicating via a previously agreed upon private symbol.Yes, we've discussed that in length with Nathan Wall :-) Sorry, I only now catched up with that. I don't have anything more to add to that discussion. So in conclusion: - we still need unknownPrivateSymbol
Is it needed? Maybe the "fail/forward" decision canbe set beforehand, when creating the proxy. Then, no trap will be called (but you cannot change the response in time; OTOH, is there a use case for it?).
Or does it do something more sophisticated then just telling "forward" or "fail" for situation that I am accessing some unknown private symbol?
- a return/throw protocol may be more suitable than a boolean return value for this "trap" Cheers, Tom
