Backticks should embed JS verbatim

As per http://coffeescript.org/#embedded use of backticks should embed javascript verbatim.

In workbench v3.2.419.21172 the following coffee script

@$('.button[tab]').click => @changeTab `this`

results in the following javacript

this.$('.button[tab]').click(function() {
    return _this.changeTab(_this);
});

but as per the coffeescript.org link above, it should result in the following javascript

this.$('.button[tab]').click(function() {
    return _this.changeTab(this);
});

Is this by design, or is this a bug with Web Workbench?

This looks like a bug (feature?) in the coffee compiler.

@$('.button[tab]').click => @changeTab `this`

Compiled with coffee 1.3.3 becomes:

// Generated by CoffeeScript 1.3.3
(function() {
  var _this = this;

  this.$('.button[tab]').click(function() {
    return _this.changeTab(_this);
  });

}).call(this);

This is apparently a known bug:

• https://github.com/jashkenas/coffee-script/issues/2184
• https://github.com/jashkenas/coffee-script/issues/1230
• https://github.com/jashkenas/coffee-script/issues/2131

By the sounds of it, they aren't going to fix it.

However I did submit an issue on github https://github.com/jashkenas/coffee-script/issues/2504

Thanks
