It's because I use Ticket<T> in situations where I need to remember (force other users to use) a sequence of functions that take arguments not necessarily constructed by others.

async fn write_buffer(buf: &mut [u8]) -> Ticket<BufferWritten>

//Best that it it's own function for readability

async fn complex_counter_logic(ctr: Arc<AtomicUsize>, ticket: Ticket<BufferWritten>) -> Ticket<ComplexCounterLogic>

//One could also place all the data in a giant struct and move that across all functions but that eventually leads to struct bloat unless we use an explicit state machine, in which case type state is better
