Mustache.js incompatibility

Assuming these declarations:

``` javascript
var template = '{{#foo}}{{bar}}{{/foo}}';
var view = {
  "foo": {
    "lol": "wut"
  },
  "bar": "Hello World!",
};
```

I would expect the same output from Handlebars and Mustache. But they are different:

``` javascript
>>> Handlebars.compile(template)(view);
""
>>> Mustache.to_html(template, view);
"Hello World!"
```
