Can not call function without parameters

[padmalcom]

It seems that I cannot call a function without parameter. I have a very simple dialog ("what time is it?", "it is 12 o'clock") that does not require a parameter. When I create a block like:

{% block %}
    {% client %}(what time is it){% endclient %}
    {% response %}{% call time %}{% endresponse %}
{% endblock %}

The response is simply "time" instead of the result of calling time. When I add a dummy variable and use {% call time:0 %} it works well.

maybe you could call {% get_current_time %} instead of {%call time %)
