CoffeeScript: self executing anonymous functions

function.coffee

# Is there a coffeescript way of doing this?

(function($, exports){
  # doing random stuff here
})(jQuery, window);

# Other than this:

( ($, exports) ->
  # doing random stuff here
)(jQuery, window)

# no syntactic sugar, but you can do:

do ($ = jQuery, exports = window) ->
  # doing random stuff here

Ah, but what do $ and exports represent? They are missing the other half of their aliases.
