is it possible to @link nested entities?

[smeijer]

Taken the example from the grapher docs:

type User @mongo(name: "users") {
    comments: [Comment] @link(to: "user")
}

type Comment @mongo(name: "comments") {
   user: User @link(field: "userId")
   post: Post @link(field: "postId")
}

type Post @mongo(name: "posts") {
    comments: [Comment] @link(to: "post")
}

How would I need to adjust the directives, if Comment was embedded in Post? When I'm removing the @mongo directive from type Comment, Meteor will throw an error mentioning that we can't use @link on types that don't have a @mongo directive.

db.users = [{ _id: 1, name: 'john' }];
db.posts = [{ comments: [{ userId: 1, body: 'hi' }] }];
