This should cause a warning:

def test : Option[Type] = null

The user probably meant to return None.

There are a few warnings I've commented out, that are more strict: warn on all nulls, on all Option.get, ...

But I like this one, because it's almost surely a bug. Will add it today, thanks for reporting.
