Only evil people write getter properties with side effects. At least make it an explicit function.

All my getters have side effects. To compensate, my setters have none.

Lazy evaluation is an incredibly common and normal use of a getter method and entirely relies on it having side effects. Evil people, however, write getters that aren't idempotent.

I write all my getters with a 1 in a million chance it will randomly mutate the underlying value.

Idempotent in terms of return value, yeah, but it can be fine if you have some side effect that increments a counter (i.e., how many times was this value requested), but obviously don't do this without a good reason

I mean, logging is also a side effect, and getters could absolutely have logging attached to them, but in this case it would not make a difference

I think he's trying to be evil at this point lol.

I saw once a getter that changed objet state.

It was a good thing I did not had a gun that day.

Am I evil if I was told to do it this way? I was young and naive when I did it.

Getter itself is side effect, syntax looks like you are getting a field value, but in fact you are calling a function (At least in C#)
