How to make the class constructor private in Ruby?

Question

class A
private
  def initialize
    puts "wtf?"
  end
end

A.new #still works and calls initialize

and

class A
private
  def self.new
    super.new
  end
end

doesn't work altogether

So what's the correct way? I want to make new private and call it via a factory method.

Answer 1

Try this:

class A
  private_class_method :new
end

Answer 2

No idea why you would wan to do that but

A.send(:private, :new) should do the trick
