Title: fix mixin example code

Previous example does not run as expected. Looping over array using `by -1` will not actually loop over the array, which throws an undefine that has no prototype thus the code will fail.

Also parentheses around mixOf are needed otherwise DepperThought will extends DeepThought only.
