Can an instance variable be treated as an array in Ruby on Rails?

Question

Here I am getting values from my model and I am putting it as an instance variable in my controller:

@users = User.where(:approved => true, :enabled => true)

now I want @users to behave as an array so that I can perform the following operation:

@users = @users | current_user

i.e an array union. any pointers ?

@users = User.where(:approved => true, :enabled => true).to_a

this would initialize the @current_user array:

@current_user = [current_user]

then I did

@users = @current_user | @users

and it worked!

Please suggest if you have a better solution.
