    Pattern matching is different.

      Yeah, I just said it since you used it with null. I used it a lot for enums

        The type matching is the most common thing I use or with. Combined with inline variables.

        if (x is string { Length: 5} s)
        {
            // do stuff with s
        }
        

        And switch expressions.
