--- Comment #2 from Josh Triplett <josh at joshtriplett dot org> --- One alternative implementation: if GCC supported a "property" attribute, specifying (optional) functions to get or set the property (with compile-time errors if attempting to get/set a property for which the corresponding function does not exist), that would completely address this issue as well: just define a no-op setter and either a constant or non-existent getter.
