How do I render Ember.Map data structure in a template?

I use Ember 2.8. There exists Map data structure in Ember. It should be iterable. However there's no examples how to enumerate through it and render it.

Assuming that both keys and values in my map are JS objects that have some 'name' set, I tried in Emblem:

each myMap.keys as |key|
  p = key.name

each myMap.values as |value|
  p = value.name

/ each myMap as |key, value|    //this one causes build error
/   p = key.name
/   p = value.name

None of these syntaxes seem to work and render something more than 'undefined' empty space.

Do any of you know how to render a Map in Ember?
