How to reference Handlebars builtin helper each's count @index in emblem

[jonakyd]

from handlerbars doc

When looping through items in each, you can optionally reference the current loop index via {{@index}}

{{#each array}}
  {{@index}}: {{this}}
{{/each}}

how do I use @index in emblem?

Need to know as well.

I bet it's not supported yet! Who wants to add it? I don't think this would be too crazy difficult if someone wanted to take a swing at it, but I'm crazy busy atm (and selfishly want to encourage contributors :)

I'd be happy to take a stab at it this weekend.

Looks like this isn't supported in Ember yet either. emberjs/ember.js#3030
Is this still on the docket?

[machty]

@patrickjholloway it's not in ember but lots of people use emblem for raw handlebars, so we should support it (And it might get added to ember at some point)

[patrickjholloway]

@machty Sounds good, I didn't realize that people were using it for raw handlebars. I worked on this a bit last night and should have a pull request ready soon.

Do we know if supporting @key for object iteration would be trivial now that we have @index? Not having @key is the only reason I still have to resort to the much more verbose handlebars.

[lai]

I totally need @key support in emblem right now. PR coming soon.
