+    This macro defines the RO5 special member functions (destructor,
+    copy+move constructors and assignment operators) as defaulted.
+
+    Normally we don't use this macro if we're fine with these functions
+    to be public; we instead leave a comment in the class declaration,
+    something like:
+
+    // compiler-generated special member functions are fine!
+
+    In some cases a class may need to redeclare these functions, for
+    instance if it wants to change their accessibility. Since
+    defaulting all five is boilerplate, use this macro instead.
+
+    Note that the default constructor is not covered, and this macro
+    will prevented its automatic generation.
