Except for a line break or semicolon between the 2nd and 3rd assignment,  
I think your pseudo code will work. Did you try it? irb is your  
friend, btw. 🙂

However, this is Ruby not Perl. There’s no need to use deeply nested  
hash structures when you want an object in Ruby.

class CustomerCode  
attr\_accessor :first\_name, :mi, :lastname  
end

array\_of\_customers.each do |cust|  
cust.first\_name = some\_first\_name  
cust.mi = some\_mi  
cust.last\_name = some\_last\_name  
p cust  
end
