| Subject: | publish: headers in $props not documented |
The "headers" key is not listed as a possible key for the $props hash.
Also, there's a empty line missing here in the Pod:
https://metacpan.org/source/JESUS/Net--RabbitMQ-0.2.8/RabbitMQ.pm#L172
which causes the subsequent lines to not be rendered in a code block. See here:
