pyrocms assign count to variable - php

Question

I would like to check if is last post from loop. I am using pyroCMS. But problem is that if i am using helper:count two times it is not working correctly. How can i assign helper:count to variable and use later variable. Is this possible?
{{ blog:posts limit="5" order-by="title" order-dir="desc" }}
{{ if { helper:count mode="subtract" } == blog:all_posts}}
<li>
<a href="{{ url }}" title="Read more about: {{ title }}">
<span class="naslovna_datum_novice">{{ helper:date format="d.m.Y" timestamp=created_on }} - </span>
{{ title }}
</a>
</li>
{{ elseif { helper:count mode="subtract" } == 5 }}
<li>
<a href="{{ url }}" title="Read more about: {{ title }}">
<span class="naslovna_datum_novice">{{ helper:date format="d.m.Y" timestamp=created_on }} - </span>
{{ title }}
</a>
</li>
{{ else }}
<li class="pikce_spodaj">
<p>
<a href="{{ url }}" title="Read more about: {{ title }}">
<span class="naslovna_datum_novice">{{ helper:date format="d.m.Y" timestamp=created_on }} - </span>
{{ title }}
</a>
</p>
</li>
{{ endif }}
{{ /blog:posts }}
So how to assign {{ helper:count mode="subtract" }} to variable?? How to assign anything to variable?

There's actually a simpler way; the streams core code adds a last property to the final item in an array - source code - that you can just query with a conditional:
{{ if last }} foo {{ endif }}
(The source code that does that is
Here's a working example for blogs I've just tested:
{{ blog:posts limit="5" order_by="title" }}
<h2>{{ title }}</h2>
[...]
{{ if last }}<p>This is the last item</p>{{ endif }}
{{ /blog:posts }}
Also, as Nick points out, you can have more than one counter.
