"if" should consider an empty array to be false

nunjucks currently considers an empty array to be true. It is common practice in jinja and its other derivatives to test for an empty array by just writing {% if arrayname %}.

From the jinja documentation:

The if statement in Jinja is comparable with the if statements of Python. In the simplest form you can use it to test if a variable is defined, not empty or not false:

{% if users %}
<ul>
{% for user in users %}
    <li>{{ user.username|e }}</li>
{% endfor %}
</ul>
{% endif %}

Yes, this one had me scratching my head. What is the workaround? update: this worked for me {% if users|length %}

In my opinion, this falls into one of the side-effects of Javascript vs Python.

In python:

not not []
=> False

And Javascript:

!![]
=> True

So I think {% if arr.length %} is more Javascript-y, and the current logic is valid. Just my opinion.
