I don't think it's a good idea. As far as I see in this file is used
```ruby
@post.comments = [Comment.new, Comment.new] # 2309
@post.comments = Array.new(2) { |id| Comment.new(id + 1) } # 2367
```

But  what I can do is to change to these lines
```ruby
comments = Array.new(11) { |id| Comment.new(id + 1) }
@post.comments = comments
```
