We’ll need to answer a few fundamental questions before we can get this documented. Here’s my short list: 1. Question for the Steering Committee: Is this an intended feature that will be carried into the future, or is this merely a side effect of the way ~~`import_tasks`~~ `include_tasks` is implemented which could disappear in a future release? 2. Does this work for any other flavors of `include_*` or `import_*`? If so, the scope of the question just got a bit creepier. (See what I did there? 🙂 3. What circumstances prevent tail recursion? ~~I’ve found by trial and error that having a `vars:` on the last task in the included task files’ last step is one such breaker.~~ [Edit: The error I incurred, “… maximum recursion depth exceeded”, was due to a variable defined in terms of itself, not that the final `include_tasks` step had a `vars:` section.] What else? Other questions? Maybe someone who knows how it’s implemented would have additional insights… Tail recursion is an “in-the-weeds” topic anyway. How do we provide enough technical detail to cover it while not overwhelming the `include_tasks` doc? Should it be split between the `include_tasks` doc and the `tips-n-tricks` page, or all in one place? Should an example be added the to `async:` doc (since async job queue management is a practical example of its application)? --- _[View the full topic](https://forum.ansible.com/t/include-tasks-docs-lack-info-on-tail-recursion/2306)._
