Looking at the source (at https://github.com/meteor/meteor/blob/master/packages/handlebars/parse.js): It doesn't look like the {{@ ..}}
set of expressions are supported with the Handlebars version packaged with Meteor.
Why Does Using {{@...}} In a Meteor Template Cause Errors?

With a simple code of
{{#each array}}
{{@index}}: {{this}}
{{/each}}
a flood of errors appears. Same happens with {{@key}}
for objects. Why does it happen?

This is definitely a frustration for me as well. In the meantime I made a handlebars helper to parse anything into named 'key' and 'value' objects:
Handlebars.registerHelper('key_value', function(context, options) {
var result = [];
_.each(context, function(value, key, list){
result.push({key:key, value:value});
})
return result;
});
This would be used with the #each
operator like:
<dl class="attributes">
{{#each key_value attributes}}
<dt>{{key}}</dt><dd>{{value}}</dd>
{{/each}}
</dl>
(I also just posted this to related Using @index in meteor #each iterator doesn't work)
