And another example:

# A chat server where @clients = [connection1, connection2...]
# message = "Hello"
# sender = "Bob"

# With normal each:
packet = BroadcastChatPacket.new("#{sender} says: #{message}")
@clients.each { |c| c.broadcast(packet) }

# With each_do:
@clients.each_do.broadcast(BroadcastChatPacket.new("#{sender} says: # 
{message}"))

Eliminating the need for the temporary variable.
