#23913: = comparison does work in templates although it shouldn't

There's no = operator documented:
https://docs.djangoproject.com/en/1.7/ref/templates/builtins/#operator
For comparisons we use the == operator as = does assign values in most
languages. In JavaScript the = assignment for example always returns true
here:
<script language="javascript">
a = 'foo';
b = 'bar';
if (a=b) {
alert('assignment always returns true here')
}
</script>
BUT in the Django templates = does work like a comparison operator:
{% if "a" = "a" %}TRUE but Django should throw an error because there's no
= operator{% endif %}
{% if "a" = "b" %}Django doesn't return True here{% endif %}
I think this is highly misleading and confusing.
