One CoffeeScript ambiguity

gistfile1.coffee

App.messageController = Ember.Object.create
  message: "Hello, world!"

# Compiles to:
# App.messageController = Ember.Object.create({
#   message: "Hello, world!"
# });

# Okay, let's refactor it and delete the message property:

App.messageController = Ember.Object.create

# Compiles to:
# App.messageController = Ember.Object.create

# Oops, your controller is now the Ember.Object#create function!

same as

return {
  foo: 123
}

and

return
{
  foo: 123
}
