If I were you, I'd just use the #include? method to see if an array
contains an element. Or, I might search for an element in the array like so:

> >> array = [1,2,4,9]
=> [1, 2, 4, 9]
>> array.detect { |e| e % 2 == 0 }
=> 2
>> array.detect { |e| e == 10 }
=> nil
>> array.detect { |e| e/2 > 2 }
=> 9

....and so on. Except you're talking about break, so this is all beside
the point.
