Equivalent of is_array in Twig

I'm working on a template and I need to check if something is an array. How do I do that in Twig?

I've tried 

{% if my_var is iterable %}
  {% for v in my_var %}
      ...
  {% endfor %}
{% else %}
  {{ my_var }}
{% endif %}

but it always prints my_var, even when my_var is really an array, as evidenced when it prints out 

Array
Array
myusername
../data/table.sqlite3

If you don't want to create a custom filter use iterable, as per the docs :

iterable checks if a variable is an array or a traversable object

{% if myVar is iterable %} ... {% endif %}

Just add a custom filter:

$twig->addFilter('is_array', new \Twig_Filter_Function('is_array'));

Then use it like this:

{% if my_var|is_array %}

Another way : 

{% if my_var.count()>1 %}
