Ah. What I meant was: if I just saw the parameter name, and not the
documentation, I believe that I would not correctly understand what it
did. I would have had to read the docs. Whereas I'm pretty sure at
some point years ago, I looked up these functions and I saw "N", and I
did understand what that did without needing it explained. If I had
seen "count" or "occurrence" I think I would have understood that
without further explanation, too.

So my point was: to me, N is more self-documenting than replace_at,
and less self-documenting than count or occurrence.

If your mileage varies on that point, so be it!
