> I couldn't figure out a way to use () for the function call, but I didn't try that hard. I (Robert) have also given it a shot, briefly, unsuccessfully. While I was critical of over-engineering this, it turns out that when we start to use `mut`, a macro is much more practical, because it doesn't create a new scope where we need a copy of a mutable reference, which of course is not allowed.
