 Member variables are always initialized in the order they are declared in the class definition, so write them in that order in the constructor initialization list. Writing them in a different order just makes the code confusing because it won't run in the order you see, and that can make it hard to see order-dependent bugs.

 If your design wants virtual dispatch into a derived class from a base class constructor or destructor for functions like `f` and `g`, you need other techniques, such as a post-constructor -- a separate member function the caller must invoke to complete initialization, which can safely call `f` and `g` because in member functions virtual calls behave normally. Some techniques for this are shown in the References. Here's a non-exhaustive list of options:

 Should destruction behave virtually? That is, should destruction through a pointer to a `base` class should be allowed? If yes, then `base`'s destructor must be public in order to be callable, and virtual otherwise calling it results in undefined behavior. Otherwise, it should be protected so that only derived classes can invoke it in their own destructors, and nonvirtual since it doesn't need to behave virtually virtual.

 **Enforcement**: The basic technique for preventing leaks is to have every resource owned by a resource handle with a suitable destructor. A checker can find "naked `new`s". Given a list of C-style allocation functions (e.g., `fopen()`), a checker can also find uses that are not managed by a resource handle. In general, "naked pointers" can be viewed with suspicion, flagged, and/or analyzed. A a complete list of resources cannot be generated without human input (the definition of "a resource" is necessarily too general), but a tool can be "parameterized" with a resource list.
