Oh, as a side note, implementing this as a single method doesn't take
care of the repeated translatable strings, as we'd need to pass the
translated string from each location we called the method from. I
suppose you could store a reference to the translated strings in init
or something, and then pass those, but that doesn't seem like a good
solution to me.
