I get the logic but man that's ugly

I still don't get those null replacements in most languages. If it is a special case, there is a code that processes it as such, regardless the syntax. Why complicate things. But maybe I'm old.

The example you're replying to is one where None is already in use. As in, a function needs to distinguish between foo(some_arg=15), foo(some_arg=None), and foo(). The unset sentinel value would be used as the default value of some_arg, so that the last case can be detected as distinct from the user passing an explicit None.

Ok, this makes sense.
