# this:
person = Struct.new(:name, :age, :human)

# …is functionally equivalent to this:
class Person
  attr_accessor :name, :age, :human
  def initialize name, age, human
    @name  = name
    @age   = age
    @human = human
  end
end

# …and can be used like so
me = person.new("Phil", 9000, true)
