Hi all,

I have a quick suggestion to improve the Loop component:

We should be able to specify a block to display if the loop source is
empty (size = 0)

<div t:type="loop" source="emptyList">

t:parameter>
</div>

I know we can do this :
<t:if test="emptyList">
       <div t:type="loop" source="emptyList">

t:parameter>
       </div>
</t:if>

BUT this will have the result of calling the "getEmptyList()" getter
in the component code twice.
If you access the database in the getter (as the docs suggest quite a
few times), this will call the database twice for nothing.

What do you guys think ?
