When looking at code that accesses a property or uses an operator that is 
overloadable, you don't usually need to know if extra processing is going on 
behind-the-scenes (typically only when optimizing). But when looking at code 
that involves a function, the distrinction between "invoked"/"not invoked" 
is almost always (if not always) a very important make-or-break matter.
