Null pointers are one thing, C# nulls (with nullable reference types enabled) are another. They behave a lot like an Option monad with the caveat that the static analysis can technically be tricked by incorrect hints.

[–] DrDeadCrash@programming.dev 2 points 3 months ago

I very much disagree with this, Null Reference Exceptions have been a huge problem in c#. Nullable reference types are a partial fix, but the question of "how do I 'return' an error from a statically typed method" is not answered there.
