Yes, that's the way I would do it.  I find almost without exception that 
the data structure I wanted was a hash, not an array.  In your first 
example, you were embedding/obscuring a piece of knowledge (0 => nam, 1 => 
dom).  Over time, I've found it more readable to make that relationship 
explicit.  As a bonus, you can expand it whenever you want, reorder it, 
etc.
