Are there more people who want this? You can always mark each message with the turn when you receive it.

The turn it is received is sometimes different from the turn it was transmitted.

For your own robots, you can also mark messages with the turn when they are sent.

The only reason it is ever different is because of turn order. Messages sent by robots later in turn order will always be received when _turns is one greater than it was when it was sent. Messages sent by robots earlier in turn order will always be received with the same _turns value.

The only way I can see this would be helpful is if you are trying to determine relative turn order of yourself with respect to opponent robots. And even then it doesn't help very much.

jamie: You can also use the turn to fight faked messages. A robot might crypt their messages using the send-turn as the seed. Imagine a robot that saves all the messages it gets and later retransmits them to confuse its enemies. When the send-turn then doesn't encrypt the message, the faker-bot is busted.

What ZeroOne said is what I had in mind.
