+Messages will be fully modelled so an actor can know *exactly* what they have to deal with, and what they can send.
+Different channels are used to make each one less clogged up, and used only for a specific purpose.
+Actors can read from/write to a specific channel, allowing them to ignore the others.
+They can then also deal with channels in different ways, maybe deprioritizing the `Test` channel.
