I would still like to find a good way to structure messages.  I'm up to 146 
in the base Msg type, and it is not flat, by counting it seems that I have 
6 message types that just hold another message type for something further 
down, which average in size from 2 for 1 of them, 4 for 3 of them, 8 for 1, 
and 21 for another (and that 21 is growing as well).  I kind of namespace 
the message type by following a naming convention of 
`<SectionCamelCase>_<SpecificMsgCamelCase>`, like this set at the top for 
    | RoomList_Init Int (List RoomDef)
    | RoomList_Joined Int (List RoomDef)
    | RoomList_Parted Int (List RoomDef)
    | RoomList_Notif Int (List MsgObj)

It works, but does not feel right, like I feel the whole Room handling 
stuff should be delegated out too, but that just ends up going further out 
of 'flat' messages that everyone keeps saying to do here, but I really feel 
like that is the wrong way and about to swap all this to a tree of messages 
as the couple that are like that work really well...  >.>
