And if you do want to do that, a rubyish way of doing that is to use
methods like select

The relevant portion of the code above could be written as

@tasks = @tasks.select {|task| task.root? || !
current_user.has_roles_for?(Task.find(task.parent_id))}

(probably a little faster too - Array#delete is O(n))
