- The codebase currently uses C++14.
- The codebase currently uses C++17.
- Use the [nullptr](http://en.cppreference.com/w/cpp/language/nullptr) type over the macro `NULL`.
- If a [range-based for loop](http://en.cppreference.com/w/cpp/language/range-for) can be used instead of container iterators, use it.
- Obviously, try not to use `goto` unless you have a *really* good reason for it.
