title: Array.include? multiple values
body: <p><code>[2, 6, 13, 99, 27].include?(2)</code> works well for checking if the array includes one value. But what if I want to check if an array includes any one from a list of multiple values? Is there a shorter way than doing <code>Array.include?(a) or Array.include?(b) or Array.include?(c) ...</code>?</p>
