# Functional:

new_person = ->(name,birthdate,gender,title,id=nil) {
  return ->(attribute) {
    return id        if attribute == :id
    return name      if attribute == :name
    return birthdate if attribute == :birthdate
    return gender    if attribute == :gender
    return title     if attribute == :title
    nil
  }
}

dave = new_person.("Dave","06-01-1974","male","Baron")
puts dave.(:name)   # => "Dave"
puts dave.(:gender) # => "male"

# OOP:

class Person
  attr_reader :id, :name, :birthdate, :gender, :title
  def initialize(name,birthdate,gender,title,id=nil)
    @id = id
    @name = name
    @birthdate = birthdate
    @gender = gender
    @title = title
  end
end

dave = Person.new("Dave","06-01-1974","male","Baron")
puts dave.name
puts dave.gender
