My own (bare and simple) implementation of ruby's Struct core class

my_struct.rb

class MyStruct
  #=> self is MyStruct
  
  def self.new(*attributes)
    #=> self is MyStruct
    Class.new do
      #=> self is the class instance
      attr_accessor(*attributes)
    end
  end
end

Dave = MyStruct.new(:name, :surname)
Fred = MyStruct.new(:age)

dave = Dave.new
dave.name = "Dave"
puts dave.name #=> Dave

dave.surname = "Thomas"
puts dave.surname  #=> Thomas
