Handlebar helper syntax in Ember CLI

In this post

Handlebar js - iterating over for basic loop

An example of a 'repeat' helper is layed out.

helper

Handlebars.registerHelper('times', function(n, block) {
    var accum = '';
    for(var i = 0; i < n; ++i)
        accum += block.fn(i);
    return accum;
});

template

{{#times 10}}
    <span>{{this}}</span>
{{/times}}

I can't seem to write this out the 'CLI' way... can someone enlighten me?

First of all, it will be it's own helper file in /helpers , and it should have a dash so the resolver recognizes it. - so I wouldn't be registering it explicitly.

Default generated helper looks like this helpers/repeat-times.js (template should be the same...)

import Ember from 'ember';

export function repeatTimes(input) {
  return input;
}

export default Ember.Handlebars.makeBoundHelper(repeatTimes);

so, no need to register, no need to set the name... I just can't find clear docs on the syntax. :/ (I took 20 or so stabs at it...)

Or should I be making a component instead? as suggested here: Block helper with ember-cli
