title: Explicit `this->` in member functions
body: <p>I have seen recommended that member functions refer to member variables using <code>this-&gt;</code> explicitly, to avoid forgetting to declare the member variable and accidentally referring to a global variable. Can anyone comment if they think this is a reasonable precaution or unnecessary verbosity that will needlessly complicate the reading of the code? Does anybody actually do this in day-to-day real-life programming?</p>
