![Unexpected function(al) equality :)](http://40.media.tumblr.com/a39b945c1fa8a2429baf0d962919a11a/tumblr_my6qxb7Ogz1rcb0d2o1_1280.jpg)

Plugin for Unexpected 10+ that overrides the `<function> to equal <function>`
assertion with an implementation that disregards whitespace. This is
accomplished by parsing and pretty-printing the functions, then doing a string
comparison.

Example:

```js
var expect = require('unexpected')
  .clone()
  .use(require('unexpected-function-equality'));

it('should consider the two functions equal', function () {
  expect(
    function (a) {
      return 123 - 456;
    },
    'to equal',
    function (a) {
      return 123 - 456;
    }
  );
});
```

This is handy when testing code that generates code.
