##### SUMMARY
The [`with_sequence` documentation](https://docs.ansible.com/ansible/latest/plugins/lookup/sequence.html) does not have enough examples to clarify.

The "Edit on GitHub" link is also broken, so it's hard to fix.

1. How to use non-inline variables:
How do you write this:
```yaml
- name: Example
  debug:
    msg: "{{ item }}"
  with_sequence: start=1 end=10
```

Like this?:
```yaml
- name: Example
  debug:
    msg: "{{ item }}"
  with_sequence:
    start: 1
    end: 10
```
(The second example doesn't actually work. What is the correct syntax without using one-liner equals statements?)

2. Show an example like this:
```yaml
- name: Example
  debug:
    msg: "{{ item }}"
  with_sequence: start=1 end="{{ number_of_things }}"
```
(It references a variable for the `end` parameter.)
