2¢ I don't think this should be an error. A Slip type is a kinda odd thing to be mapping but it should work.
quick look: https://github.com/rakudo/rakudo/blob/a61bbddc005d0188e2409a9ef8feee0c9551ab08/src/core/Any-iterable-methods.pm#L121 It just checks whether it's a Slip type but should also be checking that it's defined.
