scala - Why Some(null) isn't considered None?

Question

I am curious:

scala> Some(null) == None
res10: Boolean = false

Why isn't Some(null) transformed to None?

Answer 1

You should use Option(null) to reach the desired effect and return None.

Some(null) just creates a new Option with a defined value (hence Some) which is actually null, and there are few valid reasons to ever create one like this in real code.
