Issue #14666 has been updated by Jeff McCune. Status changed from Needs Decision to Duplicate
# Action Required # We have gone back and forth on this a lot. At the very best we're wildly inconsistent in 3.x and all of our values for undef internally evaluate to truth and internally have non-empty to_s implementations. Based on the huge number of undef related tickets in the issue tracker, I'm making a stand and saying #15329 is the real root cause of all of these issue. If you are a watcher on this ticket, please transfer your most pressing concerns to #15329. Here is the list of related "undef" issues that I've found so far: * #4692 * #5820 * #6621 * #6745 * #8778 * #8783 * #13210 * #14654 * #14677 * #14666 I am going to close this ticket as a duplicate of #15329. Again, please transfer your most pressing concerns to #15329 in an effort to consolidate all of the issues related to undef variables in the Puppet DSL.
