Also happens with simply:

    @kernel
    def foo(self, x: Option[int32]):
        y = 0 if x.is_none() else x.unwrap()
        print_rpc(y)

no need for the list.

Also happens with simply: ```python @kernel def foo(self, x: Option[int32]): y = 0 if x.is_none() else x.unwrap() print_rpc(y) ``` no need for the list.
