Returning objects -- needs explicit braces about js2coffee HOT 2 CLOSED

Ack... I just always assumed this would work. For the record, this works:

# This works as `alert({ a:2, b:3 });`
aoeu = ->
  alert
    a: 2
    b: 3

...but if it's return, it doesn't:

# This doesn't
aoeu = ->
  return
    a: 2
    b: 3
