Some of these are why I would add reconciliation to the idea. Linear types, specifically. You can encode that you only send a message once. But, without doing reconciliation with the destination, you can not be sure that it was received.

I'm torn, as the examples from small programs make a ton of sense and I largely like them. I just cannot escape that every attempt I've seen at doing these in large programs is often fairly painful. I cannot claim they are more error prone than the ones that skip out on it. I can say they are far more scarce. Such that the main error condition appears to be to stall out on delivery.
