[rabbitmq-discuss] Exchange to exchange bindings in python (pika)

Thu Sep 20 12:29:51 BST 2012

And I see a bug from my test code and what I pasted... The
channel.transport.rpc line should be:

channel.transport.rpc(Exchange.Bind(source='topicEx',
destination='anotherEx', routing_key='#'), exchange_bound,
[Exchange.BindOk])
