The English would probably read better with "on" and "do" instead of "with"
and "then".

I'm not sure what the last clause means unless it's:

    if k == i and 13 <= i and i <= 16 then ...

which is an interesting extension to standard case behavior. On the other
hand, it then forces sequential testing rather than simply accepting that as
one implementation.

But I find myself missing switch/case statements relatively rarely.
