Feature Request: Self-Executing Anonymous Functions (with variable aliasing)

[sankage]

I have been looking around to see if it already exists, but I can't find anything. I was hoping for some syntactic sugar for self-executing anonymous functions with variable aliasing.

Right now, to get this:

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

We have to do this:

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

This seems like extra work given that functions have been reduced to -> and self-executing functions to do ->

We have to do this

Nope.

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

FYI, that code won't work.

@jashkenas: what do you mean by that? It works. Compile it.

[sankage]

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

compiled is

(function($, exports) {
  if ($ == null) $ = jQuery;
  if (exports == null) exports = window;
})($, exports);

[michaelficarra]

Not for me...

$ coffee -v
CoffeeScript version 1.2.1-pre
$ coffee -bsp
do ($ = jQuery, exports = window) ->
  #stuff
(function($, exports) {})(jQuery, window);
$

Oh, lovely -- it's improved on master then, and'll go out with the next release.

[sankage]

Sweet!

See #960 for this change. It's one of the earlier commits in the set of commits since the last release.
