its copy of incorrectly closed https://bugs.ruby-lang.org/issues/17093

require 'rubygems'

class A
  def initialize(type:)
    @type = type
  end

  def b
    p type
    p type.nil?
    type = 'default' if type.nil?
    type
  end

  private

  attr_accessor :type
end

RSpec.describe A do
  let(:type) { 'whoaaa' }

  it 'return default' do
    expect(A.new(type: type).b).to eq('default')
  end

  it 'instance variable is "whoaaa"' do
    expect(A.new(type: type).instance_variable_get(:@type)).to eq(type)
  end
end

all tests green

output
A
"whoaaa"
false
  return default
  instance variable is "whoaaa"

have a look on method b, "p type.nil?" prints false, but next line type = 'default' will run
