Issue #8783 has been updated by Nan Liu.
Should we treat undef comparison similar to ANSI SQL null comparison? (the
results are unknown). If that's the case the code should be written as:
if $foo and $bar and $foo < $bar {
notify { "test": }
}
It's not as succinct, but offers clarity and should work regardless of puppet
version.

Bug #8783: Previously working equality operator case now fails on
':undef:Symbol'.
https://projects.puppetlabs.com/issues/8783
Author: Trevor Vaughan
Status: Needs Decision
Priority: High
Assignee: Nigel Kersten
Category: parser
Target version:
Affected Puppet version: 2.6.0
Keywords:
Branch:
The following code worked on 0.24.X:
<pre>
# The variables are not defined purposefully
if $foo < $bar {
notify { "test": }
}
</pre>
In the 2.6 and 2.7 series, it throws the following error:
<pre>
undefined method `<' for :undef:Symbol
</pre>
Wrapping the variables in double quotes works but it not ideal for legacy code
migration.
