One comment inline. It is painful to have a non trivial comment
that says we didn't pass a parameter for 'reason X' when maybe
it would be simpler to just pass it and not care that it always
takes the same value?
Either way this is fine.

I wonder if it's easier to just pass the level in than have the
comment?
