Title: Fixes #3762

I kept the changes at a minimum and simply introduced additional tags.
Still working on test cases for this.

Here is a sample coffee-script

```coffeescript
a = ->>
foo = 2
bar = 3

b = =>>
foo = 2
bar = 3
```

which gets compiled to

```javascript
// Generated by CoffeeScript 1.8.0
var a, b;

a = function() {
var bar, foo;
foo = 2;
bar = 3;
};

b = (function(_this) {
return function() {
var bar, foo;
foo = 2;
bar = 3;
};
})(this);
```
