 In Ruby, &method passes you!
 Most Rubyists would know what the following does.

 [1, 2, 3].map(&:to_s)

 It takes the array of numbers, calls to_s on each item, and returns an array of the return values.

 But what if you want to do the opposite? Rather than calling a method on the object, what if you want to call a method with the object as a parameter? Simple!

 ["1", "2", "3"].map(&method(:Integer))
