Won't compile list of hashes

[SpencerArtisan]

The following is valid coffeescript and should compile in emberscript too:

Todos.Todo.FIXTURES = [
id: 1
title: "Learn Ember.js"
isCompleted: true
,
id: 2
title: "Go home"
isCompleted: false
,
id: 3
title: "Profit!"
isCompleted: false
]

Error is:
/Users/spencerward/.rbenv/versions/2.0.0-p247/lib/ruby/gems/2.0.0/gems/execjs-2.0.1/lib/execjs/external_runtime.rb:68:in extract_result': Error: Syntax error on line 9, column 1: unexpected ',' (\u002C) (ExecJS::ProgramError) 06 : id: 1 07 : title: "Learn Ember.js" 08 : isCompleted: true 09 : , ^^ :~^ 10 : id: 2 11 : title: "Go home" 12 : isCompleted: false from /Users/spencerward/.rbenv/versions/2.0.0-p247/lib/ruby/gems/2.0.0/gems/execjs-2.0.1/lib/execjs/external_runtime.rb:28:inblock in exec'

I can reproduce this issue with a similar looking list of hashes.
