The only problem I see with these is the repetition -- we could just allow
"as" on {% if %}:
{% if my_bonnet.bees as bees %}
<ul class="bee list">
{% for bee in bees %}
<li>{{ bee }}</li>
{% endfor %}
</ul>
{% else %}
<span>No bees!</span>
{% endif %}
Another (halfbaked) idea: Allow separating the "in" from the {% for %}. Let a
{% for %} with no "in" make a collection "current", and then its elements can
be iterated over by, say, {% each %}:
{% for my_bonnet.bees %}
<ul class="bee list">
{% each bee %}
<li>{{ bee }}</li>
{% endeach %}
</ul>
{% empty %}
<span>No bees!</span>
{% endfor %}
The problem I see with this: it's perhaps a tad too implicit.
HTH,
