+    be useful in cases where there are unbounded numbers of
+    equivalence classes but each given invokation involves a small
+    number of methods.
+  - [ ] ContextL / context-oriented programming -- dispatch occurs on
+    hidden layer argument being an instance of an anonymous class with
+    suitably arranged superclasses -- OK because set of layers is

+    http://sauerbraten.org/lee/ecoop.pdf -- extension of Self-style
+    object system to handle multiple equally-privileged "receivers".
+    A good test case for our protocol; handled adequately with
+    generalizer being the tuple of (roles,delegations), with some
+    thought needed for method redefinitions but otherwise working
+    fine.
