Comment 2 for bug 2007650

> The documentation may not be clear enough, but where did you read that a pipeline could specify a list of list of jobs?

In your example, if you remove the `build-wheel` job then your pipeline is:

```
pipeline:
  - [test, lint]
```

which is the same as:
```
pipeline:
  -
    - test
    - lint
```

which is what I mean by a list of list of jobs.

> The most interesting bit is ... why is CI stalled even after reverting the changes?

Indeed - any ideas how we can get this restarted now that the change has been reverted?
