Hi –

Given a sniplet of code inside a class that checks for the existence of a class:

if (!defined(Class["postfix::smtprelay"])) {
    include "postfix"

One would see the following in logs:

Nov  8 09:41:24 puppet01 puppet-master[19166]: Cannot find definition Class at /etc/puppet/manifests/nodes.pp:264 on node

A couple of thoughts come to mind:

1) Should this even be reported? Is programmatic logic something that should always be displayed? Granted, the class is clearly not found because its not defined, but that would still be considered normal behavior.

2) Even if it is to be included, it should be less ambiguous. Although one can easily find and then (correctly) assume what the warning is about given this information, it does take time.

I really dislike the defined() function :(
