How to insert return value from templatetag to {% if - again

Ok, i write this:

@register.simple_tag
def get_something(data, var1, var2):
    if data:
        if var1:
            if var2:
                return { 'variable': True }
return return { 'variable': False }

but this:

{% get_something 1 0 1 %}
{% if not variable %}
    ...
{% endif %}

is still not working... Always show "..."

Try to return the value directly and use something like this:

{% get_something 1 0 1 as variable %}
{% if not variable %}
    ...
{% endif %}

I think it's not the goal of a template tag to update the global template context as it's very hard to see that the context gets updated as a user of your template tag.
