[Array reply](../../develop/reference/protocol-spec#arrays): specifically, an array with two elements:
* The first element is a [Bulk string reply](../../develop/reference/protocol-spec#bulk-strings) that represents an unsigned 64-bit number, the cursor.
* The second element is an [Array reply](../../develop/reference/protocol-spec#arrays) with the names of scanned members.
