+ * Test for UObject, currently only the classID.

+ * Usage
+ *   TESTCLASSID_NONE_DEFAULT(Foo)
+ *      --  Foo is expected to not support "poor man's RTTI".
+ *          Beginning with ICU 4.6, we only use compiler RTTI in new class hierarchies.
+ *
+ *   TESTCLASSID_NONE_CTOR(Foo, (1, 2, 3, status))
+ *      -- Combines TESTCLASSID_NONE_DEFAULT() and TESTCLASSID_CTOR().
+ *
+ *   TESTCLASSID_NONE_FACTORY(Foo, (1, 2, 3, status))
+ *      -- Combines TESTCLASSID_NONE_DEFAULT() and TESTCLASSID_FACTORY().
+ *
+ *   TESTCLASSID_ABSTRACT(Bar)
+ *      --  Bar is expected to be abstract. Only the static ID will be tested.
+ *
+ *   TESTCLASSID_DEFAULT(Foo)
+ *      --  Foo will be default-constructed.
+ *
+ *   TESTCLASSID_CTOR(Foo, (1, 2, 3, status))
+ *      -- Second argument is (parenthesized) constructor argument.
+ *          Will be called as:   new Foo ( 1, 2, 3, status)  [status is tested]
+ *
+ *   TESTCLASSID_FACTORY(Foo, fooCreateFunction(status) ) 
+ *      -- call fooCreateFunction.  'status' will be tested & reset
+ *
+ *   TESTCLASSID_FACTORY_HIDDEN(class, factory)
+ *      -- call factory.  Class is not available from a header.
+ *      'status' will be tested & reset. This only tests uniqueness.

+     * There is no delete-expression which will invoke a placement
+     * form of operator delete. You can still call the function
+     * explicitly. Example:
+     * ...
+     *     // destroy object and delete space manually
+     *     p->~T();
+     *     operator delete(p, 12);
+     *
+     * ... so that's what I am doing here.
