Subject: [ruby-core:100076] [Ruby master Bug#12251] DelegateClass(OpenStruct) behavior in 2.3.0 different from 2.2

Issue #12251 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Open to Closed

The OpenStruct changes were reverted starting around commit:e026e186f4a01aa3f6cd02ae6ef33f44f129361c, so you once again get `/` output for the program.

This came from https://github.com/ruby-grape/grape/issues/1348

~~~
require 'delegate'
require 'ostruct'

class AttributeTranslator < DelegateClass(OpenStruct)
  def initialize(attributes = {})
    ostruct = OpenStruct.new(attributes)
    super ostruct
  end
end

def namespace
  'foobar'
end

instance = AttributeTranslator.new(namespace: '/')
puts instance.namespace
~~~

Ruby 2.2.1

=> '/'

Ruby 2.3.0

=> 'foobar'

Halp?
