Hello, Question: is there a way to delete or remove a type trait once it has been defined? And/or redefine it? Consider, I've got a default type trait, something like this. template<typename T> struct throws_exceptions { static const bool value = true; }; struct my_object { //does some work with or without exception }; template<> struct throws_exceptions<my_object> { static const bool value = false; } However, in my unit test code, I want to override the default behavior for test purposes. template<> struct throws_exceptions<my_object> { static const bool value = true; } Or just leave the type trait out. Actually, I'm not sure I just considered an answer to my own question. Possibly I need to separate the traits from the underlying things being modified, and leave it as an option whether to include the defaults, or define user-provided traits.
