Subject: [ruby-core:68984] [Ruby trunk - Bug #11096] [Open] 'private' access control bypassed when ||= is used

Issue #11096 has been reported by Piotr Soko��owski.

----------------------------------------
Bug #11096: 'private' access control bypassed when ||= is used
https://bugs.ruby-lang.org/issues/11096

* Author: Piotr Soko��owski
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.3.0dev (2015-04-24 trunk 50382) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
Problematic code
~~~
class A
  def aa
    self.bb ||= 0
  end

  private

  def bb
    1
  end
end

A.new.aa
~~~
On 2.0 and 2.1 this produces 'NoMethodError: private method `bb' called for'. But since 2.2 this works and return '1'. Checked also on ruby-head from rvm.
This is similar #9907 but this allows to execute private methods by pretending that setter might be used.
