Title: Mention array sugar in guide

It's a rather useful syntax, and non-obvious.

A friend of mine is learning Rust and was trying to find a way to easily do such an initialization — he couldn't find it in the guide and was pretty surprised when I showed him. Looks like something that should be mentioned.
