How do I extend the String class, and attach a method named <code>to_bytes</code>?

<code>String#bytes</code> returns enumerator through string bytes. <pre class="prettyprint"><code>"asd".bytes => [97, 115, 100] </code></pre> In Ruby 1.9.3 the <code>#bytes</code> was returning an Enumerator so you had to add <code>.to_a</code> to convert it to an Array. Since 2.3 or maybe even earlier you don't have to add it anymore.

String#bytes returns enumerator through string bytes.

"asd".bytes => [97, 115, 100]
