+// overrides a vtable entry allocated by a superclass, that the
+// overriding method (i.e., the callee) agree with the superclass
+// on each type in the method's signature.

+// * klassItable::initialize_itable requires that, when a class fills
+// in its itables, for each non-abstract method installed in an
+// itable, the method (i.e., the callee) agree with the interface
