Oh, that's simple too. There are filters map and default.
map_name: "{{ ec2_facts.instances | map(attribute='tags.Name') | map('default', 'foobar')|list }}"
That's what I needed! I can manipulate the list like I wanted now! I looked up defaults in ansible and did not see this command. Thanks a lot.

Hey thanks for the help! It's a good step forward but I really wanted to replace undefined with some sort of placeholder. Then I can iterate through the list and replace the placeholder with the corresponding i-#.
The end result I want is a list that says: [solomon-test-2, solomon-test, i-05736d2c52da72184]
