Markt, perhaps you want to go through some sort of checking afterwards with 
something like this?

synack@eugene:~/downloads$ irb
irb(main):001:0> a = [1, 2, 3, nil, 4, 5]
[1, 2, 3, nil, 4, 5]
irb(main):002:0> a.find_all { |element| !element.nil? }
[1, 2, 3, 4, 5]

Array classes have Enumerable mixed into them so you get all the Enumerable 
functionality in the Array class, so you can say 'an Array is Enumerable' 
just like you can say 'an Array is an Object'. The find_all method is in 
Enumerable.

Happy Ruby'ng
