On the second week of my Ruby "experience" I found myself writing a 
method (for a very basic db layer) where hash.keys and hash.values could 
come in play.
So I think it's a natural need. After a short Google session I found 
others dealing with this, most of them assumed that they have same order.

Based on the answers of this thread I believe they are, however until it 
becomes documented I will use hash.to_a.transpose in production environment.
