Only when working solely with primitive operators that cannot be overloaded. Otherwise, code can easily lie. There is no shortage of methods like getFoo(), that only retrieves the latest 5 foo (unless it’s a Tuesday), but also removes the oldest foo, sends some random administrator a loosely related email, and might possible do a perfect frontflip and backflip to wrap things up (though not always, and we’ve yet to figure out why it doesn’t do the backflip before the frontflip).
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
