Greetings!
I've noticed a small problem with the assign-function and null-values.
For example, look at this loop in a template:
{foreach item=entry from=$entries}
{assign var="foo" value=$entry.title}
{if $foo}
The title is {$foo}
{/if}
{/foreach}
This will work fine as long as every entry has a title, BUT if some entry has null as title null,
assign won't do anything and keep the old value.
Wouldn't a better solution be to clear_assign a variable if a null-value is supplied?
