Issue #9992 has been updated by Zachary Scott.


 I would suggest opening a feature request if you feel strongly about adding `internal` to Ruby.

Hi,
 
I’m would like to discuss with you the concept of Internal Interfaces.
 
Currently ruby offers three access modifiers choices to set methods visibility:

- public
- protected
- private

Public methods define what we may call the Public Interface.
Private methods are private to the class and its subclasses.
Protected methods are public for the subclasses.
 
I would like to work with a new access modifier that would allow the creation of Internal methods.
 
Internal methods would be object methods that could only be called within the namespace.
 
Ex:

~~~ruby
module Foo; end

class Foo::Bar
  def baz 
     puts ‘baz’
  end
  internal :baz
end

class Foo::Qux
  def baz
     ::Foo::Bar.new.baz
  end
end
~~~

Is this something that we can think about in a future implementation of ruby?
An extra feature that would not break backward compatibility.
 
Cheers,
Daniel
