Do I understand correctly when I remark that a new BroadcastChatPacket
instance is created or each iterator call in #each_do.broadcast,

If not than it is just the same as
@clients.each{ |c| c.broadcast BCP.new... }

in this context I do not really see the practical interest though I
*obviously* like that style as I have shown above.

Well 6 months is a long time, but no I still like this magic dot notation.
