How can I delegate calls to a method to another method in Ruby?

I want to create another name for a method that already exists, e.g. I want to call slice with only. I don't want to change anything about the behavior of that original method, so it's not a redefinition, but delegation. How can I do that?

class Whatever
  def slice
    # do something
  end
  alias :only :slice
end
