Wondering if :cast may lead to non-expected sequences
Reading Elixir in Action 2019, Ch 6. Page 165 Listing 6.8 discussing cast and handle_cast and wondering if the sequence in which receive matches messages in the example can lead to a situation that a call, sent immediately after cast may somehow appear handled “out of sync” from the caller perspective.

Messages are handled in the order they are received. The order of matches in the receive block has no effect on the order in which messages are handled. For each message received, it will run through each option in the receive until it finds a match.

It cannot. When A sends B a message, B will always see messages from A in the order that A sent them. This is guaranteed.
