If you have ever done even a humble sized JavaScript project, you know what I mean. Wrong result when evaluating multi-line boolean statement in Ansible yaml file.

However, we recommend you use the Fully Qualified Collection Name (FQCN) ansible. g. Because conditionals require boolean input (a test must evaluate as True to trigger the condition), you must apply the | bool filter to non-boolean variables, such as string variables with content like ‘yes’, ‘on’, ‘1’, or ‘true’. It is a built-in feature of Ansible to use the default variable if the variable is not defined.
