Daniel Dekany commented on FREEMARKER-21:
-----------------------------------------

{{as}} clashes with {{<#list xs as x>}}... so it should be {{into}} or some=
thing like that.

> Repeating stuff is annoying, especially in programming.
> Therefore this is annoying:
> {code}
> <#if someVariable.someMethod.someProperty??>
> <div>${someVariable.someMethod.someProperty}</div>
> </#if>
> {code}
> This would be better:
> {code}
> <#if someVariable.someMethod.someProperty?? as value>
> <div>${value}</div>
> </#if>
> {code}
> Not talking about the fact that it could only be evaluated once.
