Yes, meta_type is an attribute of type string, but I don't understand your reasons. Acquisition, obviously, is not implemented in strings, but if the object containing meta_type attribute inherits from Acquisition.Implicit it should work. In fact, it works for Zope 2.7.0 to 2.7.2. The problem appears in Zope 2.7.3, and I think that the problem is the change I mentioned in AccessControl/cAccessControl.c and AccessControl/ImplPython.py. I suppose this change is for some reasonable reason, but if it breaks security validations throught implicit acqusition I think the change should be considered.

AFAIK Tres is working on this. I was unable to produce a simple example case, but more recently Stefan Holek (I think) was. The last I saw was Tres saying "Aargh!" on the 13th, then on the 14th saying he's unable to produce good test cases.

And that's the problem. Tres' patch removed "DWIM" code. I'm not sure what that meant (I know what DWIM stands for ;) ... and I'm unable to state exactly (in a test case) what it is that my code does that invokes the DWIM'y code.
