>                 Key: FREEMARKER-70
>                 URL: https://issues.apache.org/jira/browse/FREEMARKER-70
>             Project: Apache Freemarker
>          Issue Type: Bug
>          Components: engine
>    Affects Versions: 2.3.26-incubating
>            Reporter: Bill Parkinson
>
> When invoking a macro inside of a #list  the loop variable is not in scope to be used
resolving the argument values to the macro call.
> Example
> {code:java}
> <#macro button caption>
> content irrelevant.
> </#macro>
> <#list ["a","b","c"]>
> <#items as loopvar>
> ${loopvar?counter} -- works
> ${loopvar?index} -- works
> <p class="${loopvar?index}"> -- works
> <@button caption="${loopvar?index}" /> -- FAILS
> </#items>
> </#list>
> {code}
> The @button macro call fails with the message:
> The left hand operand of ?index must be a loop variable, but there's no loop variable
in scope with this name: loopvar
> Shouldn't loopvar be in scope for evaluating those macro argument values?
