You’re right that I want to pattern match on the header. I want the header to be defined in the module that handles the actual packet though. Otherwise you end up with a module that is nothing but a large list mapping the header numbers to modules. I don’t want to separate that information.
If I was able to get every module that has use Packet, header: 1 or implements a Packet behaviour, or every module with a @packet_header attribute, then I could build the list without having to list them all out manually.
