I consider this function bad, as it relies on #list. This means it's O(log n) + O(n), but it could be changed to O(n) by changing it to:
You can ignore the log n part. O(n + log n) ≃ O(n).


There's a bit of a difference between O(n + log n) and O(n) + O(log n) tho... And I thought the part about cross-impl consistency was more important?

The way I learned the O notation, and the way it is described in Wikipedia O(n + log n) is the same as O(n) + O(log n) and O(n + log n) is the same as O(n)

The O notation does NOT define runtime of a function, only its order.
