Feature: slice of $@ in Arguments

[mgvalverde]

Hi,

First thanks for book, I have been using it recently and I find it pretty handy.

The second, I think it would be useful to add some example explaining how to access to a slice of $@, in the section "Arguments" .
Something like the solution found here.

Thanks!
