The following are all equivalent:

    request(url, (response) ->
      handle response
    , (error) ->
      handle error
    )

    request(url, 
      (response) ->
        handle response
      (error) ->
        handle error
    )

    request(url 
      (response) ->
        handle response
      (error) ->
        handle error
    )

    request url, \
      (response) ->
        handle response
      ,
      (error) ->
        handle error

    request url, (response) ->
        handle response
      ,
      (error) ->
        handle error

It's very reasonable for a JS developer to be confused when seeing those.
