Being a python newb I did not know that any error in property getters result in an AttributeError. I understand the rationale behind it, but it makes me a little anxious to have my "security" code blowing up silently and leaving the traversal "layer" in an unexpected state.

What would be nice is if the ACLAuthorizationPolicy could look out for acl that is a callable and deal with it that way. then errors will bubble up properly.

For now, I've embraced and extended for batterii's innovation platform, but I'm of the opinion it might be desired in pyramid as well.

FTR I think the behavior your describe (any error in a property getter causing AttributeError) is actually a CPython bug, which may have been fixed in the latest version.

I've merged this fix in aae62a0 and recommended its usage in the docs. Thanks for this solution.
