Could you please add working examples on loops

Hi, I'm currently having issues getting the for-loop example to work.

Could you please help me with this?

Thanks a lot ...

```
  {%- for person in ['Bob', 'Joe', 'Jen', 'Amy'] %}
  * {{ person }} will come to the party!
  {%- endfor %}


  {% for i in range(11) %}
  { { i } }
  {% endfor %}

```

results in:  Failure! Could not parse template.
