Hash keys can be any object. So your hash, h, has one key, the object v.

Take another hash real quick, we'll call it hash.

hash = Hash.new

hash['rabbit'] = 'cute' # 'cute'
hash['blue'] # nil

The value for any hash key not defined is nil (unless you explicitly 
tell the hash during instantiation to use another value).

So just because you're using the value of v as a key in your hash, does 
not mean that v2 is automatically another key in your hash.
