Firefox debugger bug

1. Create a gist if you haven't already.
2. Clone your gist:

   # make sure to replace `<hash>` with your gist's hash

describe('this should cause tests to fail', function(){
    // this will cause an exception
    // causing mocha to ignore this whole file
    var hello = JSON.parse('{"hello":}');
    
    it('should something', function(){
        // magic
        assert.equal(true, true);
    })
});
