Comment:
After staring at the code for a few minutes, I also don’t see a difference
– both evaluate `n` first, and then go down the list in the obvious
manner.
Some archaeology reveals: ceb68b9118fa883e88abfaa532fc78f6640cf17f changed
the prelude definition, and before the change, `!!` would evaluate the
list before the number.
So you are right, the comment is wrong. I just removed it.
