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
