+    Proxy objects are weak references that attempt to behave like the

+    act as a weak reference relies on a fundamental mutability that
+    will cause failures when used as dictionary keys -- even if the
+    proper hash value is computed before the referent dies, the
+    resulting proxy cannot be used as a dictionary key since it cannot
+    be compared once the referent has expired, and comparability is
