`println!` adds references (&) to its arguments, to avoid moving them.
This is undesirable here, because it is extremely error-prone to take
references to `static mut`s. We could `println!("{}", {counter})`, but
this is somewhat exotic syntax and just sticking with `dbg!` also
avoids this problem as it does not add references.
