Title: Fix problem with cast comparison in exact-lenght

The exact-lenght validator is not working

Coffe script creates

```javascript
return function(v) {
return v.length === arg;
};
```

v.length returns a Numeric object and arg is a string so it has to be cast to number because it will be false always.
