+## Warnings
+
+Accessing a nested attribute will throw a warning in your console, because it's safer to use the getter syntax above.  To silence these warnings, add an argument of `{silent: true}` to `get()`:
+
+```javascript
+user.get('addresses[0]'); // gives a warning in your console
+user.get('addresses[0]', {silent:true}); // (silent)
+```
