I don't think so. Suppose I have an object A protected by ACLs. Now I
write a new method

def doit():
  A.doit()

Question 1. What is the calling object?
Question 2. Assuming it is "the doit function", and assuming the doit
function is not listed in the ACL: Will the call be executed?
If yes: What is the purpose of the ACL then?
If no: I believe the proposal is not usable in practice. For example,
what should be the ACL on calling open()?
