Lookup helper won't work with block parameters

[steinerkelvin]

{{#each names as |name id|}}
  {{name}} <br>
  {{lookup . 'name'}} <br>
{{/each}}

works for {{name}} but not for {{lookup . 'name'}}

jsfiddle

I intend to use this with dinamic partials:
{{> (lookup . 'name') }}

I can't say if this is supposed to work, since the block parameters are not part of the input object.
I think this needs to be specified (#1277, "We need a spec")

Do you have to use "lookup" to solve your problem. I think you could just use {{> (name)}} like in https://jsfiddle.net/vva7musq/9/
