    It might be an absolutely adequate method. Imagine that is C++. operator-- is overloaded and controls some machinery. You can't just command capacity = currSize. Process is important.

    Yes. Sometimes you're limited by the hardware you're controlling. This code is a bit hard to justify with that excuse though. Normally your code would do a read from hardware to see if the value decremented and then repeat the write. (Possibly a sleep/yield in there if required.)

      That is why it is loved: it allows you to use ideas/objects the same way as you do as an engineer. Super cool.

      yes, but in this particular case I wouldn't want to second guess my decrement operation just happens to also be calling the white house or whatnot. Just make a method.

          If those are normal integers, the compiler optimizes that to a simple compare and branch/cmov.

                      Until the next person with a slightly different mental way of defining things comes along. Or just a future version of you.

                        You wouldn't second guess the decrement operation if it's a basic type like int. If I opt into using complex types, then I am responsible to understand/establish/forbid the syntactic sugar for it. That's the mindset I often use to program C++

                          Yeah, just to say it more clearly: that kind of thing is why lots of people out there insist that operator overloading is a bad idea.

                          And yeah, it's a C++ thing that mostly doesn't happen in other languages.

                            That's just life of a C++ programmer: you second guess everything, and there are still optimization you haven't tried, and pitfalls you haven't got into

                                  Sincerely agree. Explicit is better then implicit, that’s a general engineering axiom.

                                  Instead of overloading and making the next maintainer hunt for overloads, a clearly named function that does the critical steps would make the code immensely more maintainable. C++ is C gone wild.
